It's driving me mad.
Neighbours have 2 teenage kids who stay up all night and open and close said creaky door (I believe it is the bathroom door) waking me up practically every hour during the night.
I've tried to have a reasonable conversation with neighbours but they are completely stonewalling the issue, literally ignored me when I went round to try and resolve the problem. Although the issue may have been that the parents are of Turkish origin and possibly don't speak much english. However, the 2 kids were there and DO speak perfectly good english.
The following day I got a note through the letterbox saying that it didn't bother them so they weren't going to do anything about it. 
I don't understand why they can't just put a blob of grease on the hinges and solve the problem.
WWYD?
