I don't know if I'm in the right place but here goes. our neighbours are constantly shouting banging the walls connecting them to us. banging up and down the stairs. some nights they're doing it at 2 or 3 in the morning and can wake me up (I'm a light sleeper) and even my new born (who's a heavy sleeper nothing wakes him up).
is there anything I can do. I can't go round and talk to them as they're known to be aggressive.
