I have lovely neighbours one side and complete idiots the other. My cats set my burglar alarm off one night (about 9pm) and whilst I appreciate it must have been really really really annoying (and in fact have never used the alarm since) it was completely unnecessary to put a note through my door full of f's and w's and c's. A polite note would have sufficed and would have been met by a polite and genuine apology and a bottle of wine for the inconvenience. They still got an apology (on the basis I will not stoop to that level), but it was extremely threatening and its not as if I did it on purpose!!!! Consequently, my alarm was not on, when someone broke in.
