Ok.. imo OP just likes to suffer or is not actually suffering or is trolling.
I see no other reason for posting at bitcoin forum about problems with the neighbours instead of actually doing something.
I wouldn't call it suffering, but a minor annoyance I shouldn't have to deal with in the comfort and privacy of my own home. He can do whatever he wants in the comfort and privacy of his own home as long as it doesn't negatively affect me. It
is negatively affecting me and he's often neglecting or not looking after his child in the process.
And no, I'm not trolling. This is the off-topic forum of a Bitcoin forum. Anything goes in here. I was just venting and asking for advice on how to best deal with the situation.
Perhaps inviting him over to some pizza and fun games would be a good idea, then after having had fun for a couple hours, and you're both jolly good friends, you nicely and kindly tell him about how his habits are somewhat of a situation for you, and if he might considering helping finding a solution to it.
You'd be surprised at home people react when people are nice to them. When people are not nice, the recipient usually get a very low motivation for behaving a good way.
