Oh don't rise to it, wait for them to come to your face! Just smile and say you don't see the problem...trust me it works better than stooping to your level...
Ah who the heck am I kidding, start screaming through the walls yourself!
We have chickens and our neighbours said that their daughter had to have blood tests because of the stress they were causing her through the noise levels. (they are free range, and like to point out, only have 2 and they are out of their way totally (large garden) and she works nights so not my fault anyway about noise during the day...oh and she is 25!) they called the environmental health people and reported us. This was a few years back now, so can assume they were in the wrong, not us. Also this came from the neighbours that do DIY at all times of the night and day, play music so loud it blares through their garage, through ours and into our house! I have NEVER complained to them, moaned privately but never to them. So when they came round mine to say that they had reported us I just laughed in his face and told him I'm up for the challenge and slammed the door in his face. Now he avoids us every time he sees us...so we blatantly make sure we say hello to them ha ha.
Flipping hate knobby neighbours.
