Oh blimey. We live in a Victorian terraced house, mid terrace, and have one neighbour who is occasionally a bit noisy. He's a single gent of a certain age who loves top gear (or whatever it's called now) and so we have gotten used to hearing Jezza Clarkson and friends blasting through the wall at high volumes whenever there's a new series out (he loves it so much that he has been known to watch the same ep back-to-back three times in a row until the wee small hours. He also occasionally plays loud thumping music and it can go on until 4 or 5 in the morning. We've never bothered too much - we think he turns the volume up when he's had a drink and to be honest with two small kids (one who was a dreadful sleeper until recently) we've always assumed we give as good as we get. He has a lodger (or did until Monday) and is quiet when they are/we're in. We are civil with him (have given him the odd lift, let him use our garden waste bin etc) but not friendly if you know why I mean.
We're not sure what's happening but the lodger moved out last monday and since 5pm yesterday (with a small break between 5am and 11am) he has been playing incredibly loud music and shouting "c*nt" and "fuckers" so loudly that we can hear it in our house, our elderly neighbour heard it and we also could still hear him in the park across the road. DP knocked on the door a bit ago to ask if he was ok but he didn't answer and we've been in to the elderly neighbour (who is on the other side of him) to check she's ok. We don't know what to do next. Is he having a breakdown? Is he drunk/high? Is this the new normal? I'm reluctant to get a third party involved because he is the sort of man who could make life v difficult if he didn't like you. I also don't want it on a house report if we were to move. We thought about putting a note through but are worried he will misconstrue it and the situation will escalate. Other than trying to speak to him face to face, wwyd??
