I've lived in 3 hoods- Compton, east side Buffalo, and in the BronxI've also lived in the slums of Brazil and the hood aint nuthin compared to a 3rd world slumEach hood is different, some are more dangerous than othersI suppose I'll make for you a listThe Hood 1The media over exaggerates the violence- heck sometimes they even lie2The cops see the gangs, they see the gangs do shyt but they turn the other way(except in Niagara Falls where they do really crack down) 3People think there's no such thing as a White hoodTry Lovejoy in the city of Buffalo, NY4There are rarely jobs and sadly in some hoods the liquor store is the biggest thing aroundThe jobs that come don't stay too long5The hood is predominately Black and Latino (some have higher rates of Arab and all hoods have a small % of White people)Depending on your area, some hoods have a high Native American pop50% of Native Americans live in urban areas- mostly in poor areas6Corrupt copsNot everyone in the hood hates copsI mean if I need them, I'll call (I never said snitch)However, I have seen cops (in America) deal drugs to 12 yr olds7The rent is low so all types of shady people come inFrom crack users to crack dealersForget about using the elevator in your project housing unless you like needles and pee8Most people in the hood are actually nice people9The most common drug here is ganja (weed) we can't afford anything more unless you turnin tricks for cokeMost of the hardcore drugs (coke) is sold in the burbs10People who deserve to be on welfare can't get on it and people who abuse the welfare system are on it (but sometimes ppl who need it do get it) 11Some people work hard and want out, other people make excuses for themselves 12Teachers tend to think the kids are all headed down the wrong path or they all come from dysfunctional homesI am a teacher, I can say thatNot all kids in the hood have unhappy homes, some have good homesAgain the hood is NOTHING compared to a 3rd world slum
Q:I read a great book earlier this year but I cant remember the titleIt was about a girl whos best friend died and she meets a mysterious boy at the funeralThey meet up several times and get to know each otherShe eventually falls in love with himShe finds out in the end that he is a ghost of a boy who died years agoIt takes place in the town where the headless horseman took placeThe town of crane maybe? After icabod crane? Please sombody know this book ive been looking EVERYWHERE.
I would guess that a greenish-blue tinge indicates that it is platedThe color is coming from the copper that bonds the silver to the base metalYou can use a universal cleaner that works on both copper and silver or you may want to try vinegar and salt first then rinse it really well before using a silver cleaning solutionThere are also several folk remedies for removing copper oxidesThese include scrubbing with buttermilk, ketchup, olive oil or baking sodaThese may all work (all have their own form of acid) but whether they work for you is indeterminableIf there are any semi-precious stones be sure to use a cleaning solution that is safe on themSoft stones like turquoise or pearls may be damagedIf the jewelry is of significant value I suggest having it professionally cleaned.
Q:I have the platinum chip, just killed Benny, spoke to Yes-Man, and want to go to MrHouse to decide how to continueBoone is my companion but he waits outsideI can't initiate a dialogue with Victor by the elevator nor activate the elevator itself, it's like I'm stuck in the Lucky 38 lobby with no way to go upHelp!
Cliff, he said frame mounts, not engine block mounts clamshells The frame part of engine mount is bolted on with 3 bolts and nuts per side You need to get engine out of way if it's still in place (you can lift it high enough with out fully removing it) Then you have to fight with getting to the bolts that holds mounts inIIRC they are 15mm bolt headsYou need alot of 3/8 drive extensions, wobble joints and some wrenchsI even heated and bent one box end wrench to aangle I needed for doing this Keep you some axle/wheel bearing grease handy to put on wrench/socket to hold nuts will you wizzle them through K member You need to hold one side as you turn the other sideIt's best to have a helper when doing this.

I think you're trying to compare apples to oranges hereBoth make a very good materialHemp is more in line with cotton than wool, i.efor insulating qualitiesA hemp T-shirt is just as good as cotton one, but would not be as warm as a wool oneThe advantage to hemp, though, is the environment in which it will growIn that it is really just a big weed, it will grow in some of the worst conditions that other crops would die off inI'm in South CarolinaThere is a big push in this area to get tobacco farmers to stop growing tobacco and switch to hempThey both like this clayey, nutrient poor soilThe problem we're encountering is the negative pot smoking stereotype that is associated with hempHopefully we'll be able to work past that.

Q:I have a 4 string stagg BC300 bass guitar.Its now a 3 string.How do you re-string one of these bass's?Also if I get good at bass is it a good idea to learn to play electric guitar?
Buy the appropriate stringInvestigate the bridge end, to see how the strings are attached There will be an attachment with 4 holes in it, probablyThread the new string through the hole, run it over the bridge, seating it correctly in the saddle(There will be a ball end on the string that will rest against the attachment) then take the end up to the headPush the end through the hole in the machine head post, wind the string round a couple of times then turn the machine head peg until it is in tunePlaying the electric guitar is always a good ideaHope this helps.
Q:I've learned that Chinese is one of them:quot;Ma ma ma ma ma?quot; (using five different tones) it means:quot;Is Mother's hemp to scold the horse?quot; or something like that.PLEASE, NO NONSENSE ANSWERS!
Hey you are wise! All Chinese characters have only one syllable,so Chinese can do that.In my mother tongue (my family is of Chinese ethic group),which is similar with Thai language, ma ma ma ? means is it a horse or a dog? And I think ma ,ma means Come here,doggy in ThaiPSall of the three languages have at least 4 tones I bet no language can do this except Chinese: 施氏食狮史 石室诗士施士,嗜狮,誓食十狮。氏时时适市视狮。十时,适十狮适市,是时,适施氏Write in Pinyin,it's like this: shi shi shi shi shi shi shi shi shi shi shi,shi shi,shi shi shi shi.shi shi shi shi shi shi shi.shi shi,shi shi shi shi shi,shi shi,shi shi shi shi shi.shi shi shi shi,shi shi shi ,shi shi shi shi shi shi,shi shi shi shi shi,shi shi shi,shi shi shi,shi shi shi shi shi shi.shi shi shi,shi shi shi shi shi shi shi.shi shi,shi shi shi shi shi shi,shi shi shi shiTranslation: History of Shi Eating Lions A poet lived in a stone house ,whose family name was Shi,Liked to eat lions,and he vowed that he would eat ten lions one day.Shi often went to the market to see if there was any lionsTen o'clock,there were ten lions being sold,at the moment,Shi was on the market.He saw the ten lions and killed them then pick up the bodiesHe went back to the stone house,and it was wet there.So he asked his maid to clean it.After the house was cleaned,Shi began to eat the lions.When he was eating,he found that the ten lions were made of stoneAny other passages in different languages???
Q:I'm a truck driverHow do I load heavy materials into my truck?
Q:Wanting to buy a guitarneed help :) (read inside, please!)?
it is variety of humorous the way you plug in Michelle hates u.s., complains appropriate to the conflict, undermines the troops in that first assertionof direction that i admire u.sextremely is an oppurtunistic quote on her behalf, making it an straight forward aim on Michelle's behalf (even nevertheless the present First woman Laura Bush suggested she misspoke)And Cindy McCain does have a sordid history herselfShe did sleep with a married guy (McCain divorced his spouse and married Cindy in 1980, they began their relationship in 1979)Cindy additionally replaced right into a rodeo queen, a cheerleader at USC, and had inherited a fortuneShe has spent noticeably a lot all of her existence rolling in money, very like Paris Hilton or George WBushTo me, Cindy is attempting so complicated to be like the prototypical 50's housewife, like Donna Reed, yet coming up short (as evidenced via her theft of prescription pills and repeated tries to bypass off recipes from the food community as her family individuals's tradtional recipes, and via what John McCain says plastering makeup on like a trollop, he oftentimes referred to as her a cnt)So how does that parent into elitism? So are you able to call her an adulterer, a thief, an elitist? To me, Cindy McCain is variety of a grown woman who needs to be a Barbie doll or Donna Reedvariety of the alternative of Michelle who's superior, slightly extra of a fighter, than her counterpart.
Q:The same jobs here that pay $50-$100,000 a year like a garbage man, truck driver or crane operator only pay $12-$15 an hour in the Midwest.
I hope the people realize that California had a republican governor that got them to this pointJust like the democrat governor of North Carolina took the blame for it's hardships, california has to point to it's past republican governor.
