I'm not sure that there is really a 'normal'. All people are different. We all probably have annoying habits. My neighbours parrots are pretty vocal. Sometimes it's funny. They have the telephone ring pretty well mastered. Other times, when I need to concentrate, it drives me up the wall. That's nothing though, compared to when I lived near student halls of residence. Regular drunken arguments in the streets in the early hours. I did eventually complain but- what are they really going to do? They said they were working with police but, the police aren't going to bother with a bit of noise when they have other serious crime to deal with.
It's kind of tricky really because- unless it's over a certain noise level and, if it's not at an anti social hour, I doubt he's actually breaking the law. You could try to talk to him but then, there's always the risk of creating bad blood with someone you live right next door to. I'm sorry though. It can be maddening- I know.
