Reminds me of a guy I used to work with, Brian.
A new couple moved next door to him, and were doing up the house, hammering/drilling etc til well past 11pm. after a bit he knocked on the door and asked them if they would be mindful of the sound & time, he got a mouthful of abuse & threats in response.
Now Brian wasn`t scared of anyone, he was ex military and a boxing coach, but he just smiled, left and thought "you`ll get yours".
A couple of years later the couple had a baby, whose bedroom was next to Brians house. In the evenings when he got home from work, every hour on the hour he would place a piece of wood onto the adjoining wall and hit it with a hammer until 11pm/midnight. For some reason this woke up the baby who started crying loudly every time.
When the man of the house (and chief responder/hurler of previously mentioned abuse & threats) asked him to stop he replied as per the response he had received years before.
