Hmmm, same here. It depends on the people. I mean, there's no law of nature which says that all drug addicts, criminals, heavy drinkers and emotionally unstable people are bound to be noisy, obnoxious and constantly attempting to steal your stuff. I've known and lived near quite a range of the listed (obviously not for many, many years due to my age, but in some pretty ****** place), and they range in unputtableupnesswith as much as everyone else does. Some make a nuisance of themselves and others don't.
Noisy neighbours don't bother me a great deal as I seem to have a kind of inbuilt selective deafness. If music is really rhythmic, it's fine for me to sleep to up until quite a loud volume. Having said that, I've never suffered neighbours who play music/TV literally so loud that the walls shake -
that would piss me off. Loud shouting and/or barking dogs/crying babies at unearthly hours don't really get to me.
What
is annoying is if you have neighbours who constantly pick on you, e.g. vandalising your house/garden, knock-and-run kids, throwing things at the windows, peering through the windows, hanging out outside yelling things... etc. etc.

kashii: I'm quite an easy-going person, but these things bug me because if you're not careful they start to impinge on the way you live your life. And why the hell should I let other people's behaviour dictate mine?

kashii: I'm damned if I'm going to cringe in my den like a mouse! :angryfire:
Political extremists could be annoying as neighbours, I guess, if they kept constantly buttonholing you and talking for ages about their views.
