I know the title doesn't sound very nice but bare with me.
I live on a quiet road which leads to a small shopping street. Since around 4pm today a car has been parked outside my house, not bothered about this, not blocking the drive. However the alarm has been going off since about 5! Not a normal car alarm but an annoying high pitched beep which stops every 60 seconds then carries on! The neighbours have been out and a few of them went down to the shops and the pub and enquired about the owner, no luck. We are the only houses around here and the car definitely doesn't belong to anyone in the road or their visitors. We have phoned 101 and community support officers came round, but because not causing an obstruction they can't do anything! 
I have a 9week old colicky baby who doesn't sleep at the best of times, and my OH is on a 14 hrs shift starting at 5am. Is it bad that I want the battery to die and for the owners to be stuck on our road so that the neighbours can give them an ear full?!
