Can't tell you how many hours of sleep I've lost because of those noise makers that rude and thoughtless people impose on me and others. There are at least four sets of those loud and obnoxious things I can clearly hear in my bedroom at 3 am. If I wanted to hear loud bells in the middle of the night I'd leave my alarm clock on. I don't know why people think it's ok to force others to listen to that obnoxious noise all night, anymore than thinking it's ok to blast their stereo. Some people are just pigs.
