i have just spent the last 2 hours destroying my house and cleaning it and then destroying it again looking for my car keys. i looked everywhere, the fridge and pantry, under the couch, in all the clothes, the yard, even behind the washer and dryer. then about an hour or so into my search i hear it beep like the buttons had been pushed so i started all over again. it kept beeping and i was becoming slightly frantic and to top it off my son was crying for a bottle and a change. so i decided to take a break and take care of him. low and behold he had taken them (no idea how) and stuck them in his diaper and every time he would sit down the car would beep. he is so so very lucky he is cute.
