I have a three strike rule for most things. Annoy me once, I'll ask you nicely to cut it out. Annoy me twice, I'll explain in depth as to exactly how you're annoying me and what can be done to rectify the situation to mutual benefit. Annoy me again after that and I'll break you like Ivan Drago.
My neighbour is a royal prick. Blasts his music at max volume, always has rowdy guests and constantly fights with his missus, but the moment I play my guitar he bitches that it's too loud and that he'll file complaints. Landlord doesn't give a smeg, he's on my side, so whenever they bitch about the music I crank my amp up another notch. Generic crap rap is no match for Hall of the Mountain King.
