I disagree, not everyone knows what they are doing is wrong...it might be something that irritates YOU...not them. and after a while it just makes you crazy. so the ball is in your court. either put up with it or tell them stop.

people don't have spy scopes into other folks heads. they can't be aware at all times of what irks others. sure some stuff is obvious but others are not. regardless, if something another person does bothers you and you don't say anything about it, well any suffering that occurs you own.
they may have no idea they are even doing something annoying..and at that point the ball goes to their court.
