it sounds like you live with your mother in law. if thats the case then move out of her house and get our own home. it also sounds like your problems are petty. try and look at the good things your mother in law does for you. if she's letting you live in her home then thats defiantly a good thing she does for you. but if you really cant stand your fiance's mom then you need to rethink you relationship with your husband, because once you get married you'll be married to his mother also

Lightning rods don't actually divert lightning if it hits your house. What they actually do is in theory is create an equilibrium of electrons in the air so as to not attract lightning in the first place. If lightning hits its going where it wants to plane and simple. I have controls and machinery at work that are triple grounded to try to keep them safe and lightning still takes them out. The main reason you hardly see them anymore, is the cost of installing systems, they have to be special licensed contractors, and they are few and far between now days.
Q:2003 Mercedez Benz C240 Alarm
Not so much a draw issue as it could be a wiring issue. If the alarm was aftermarket, it could conceivably be send false signals to the cars ECM, which then disables the ignition circuitry. I had a car with an aftermarket system and I ripped it out, because it kept the car from starting every so often.
Q:I have a 2006 Mazda Tribute that currently has All-Season tires bought in October (I bought about 2 1/2 weeks ago) and I'm wanting to do some tire replacement with something a bit wider and a bit bigger. I was on Tirerack and found a sweet tire with great reviews that are All Seasoners.My mom insists that, Living in Alaska (which is mostly flat in my area) with a lot of ice, I need heavy-duty snow tires or even Studded.Your opinion? Can I get away with kick-*** all-seasons?
its the cockroaches. It happens to me each and all the time. they on no account hear when I say get the f**ok out, yet notwithstanding, its some thing I could stay with. They flow slowly everywhere in the alarm and that they are continually yelling at it till the alarm gets so mad that it in simple terms screams its undesirable noise. perchance you may positioned insect repellent on it or somnething. attempt to seize the cockroaches out with a stunning meal too. i offered them mcdonalds one time nd they walked perfect out nd began munching on a snackwrap. yet yea in case you have cockroaches in simple terms chillen on your alarm, thats in all risk the project. additionally, in case you ever get the prospect to fulfill megan fox, run her over with a trailer and produce her to my abode, comparable is going for you Pam Anderson(i visit locate you, you grimy tramp!) in case you meet Jessica Alba deliver her to my place alive bc the flaws that i might do to her are insane.
Q:how to get speed bumps put in my neighborhood?who do I go to?
Is this an older house with the smoke detector wired into the home? (Some older ones were actually powered off of the home power!) If so, it was probably illegal to sell the house with those ancient smoke detectors. You also may have wiring if you home has a security system. Otherwise, it is just battery powered. Just see if you can remove it. If there are no wires coming out of the wall or ceiling, it is just battery powered without security wiring. Try changing the battery first, as Texperson suggested. If that doesn't work, buy a new smoke detector. If you need a new one and there is no security wiring, it is not worth the time or trouble to call an electrician, especially if your home warranty has a deductible. You can buy a good brand of smoke detector for $9 to $20 from places like Lowe's, Home Depot, or Walmart; buy a Kidde brand or a First Alert brand. Also, an regular electrician will only be able to replace your smoke detector, which is a five minute job, he/she will not be able to repair it since they would required special certifications and test equipment to do so. By that time, you are in the hundreds of dollars price range for what you can do yourself for about $10. It would only require two screws, at most, to install one of these.
Q:We have a Lifesaver brand Serial Number 2673412, model number 1275. It was installed when the house was built in 1998.
