So we used to have a smoke detector in our kitchen. Unfortunately, it also used to be right above the stove and microwave, so whenever something was steaming, or even if we cooked something in the microwave, it would go off. So we took it out, and the problem was solved. Apparently it was still keeping track of the battery life however, because at about 10:30 tonight, it started to beep. the only problem is that it was back in J's room, hidden behind a very heavy tool box (we still have no idea how it got there). so we got to go digging through everything to try and find it. it took us a a good half hour or more to find it. and both Drew and I were very surprised that J stayed asleep through it all. especially since we had some rather...close calls... with noisy items that were moved.
