Is it normal i hate groups of people hanging around in one place?

Do you mean loitering?

Oh, you mean like all those people at bars and clubs that are "hanging around in groups with nothing better to do"?
Or all those spectators a sports events that are "hanging around in groups with nothing better to do"?
Just when does "hanging around in groups with nothing better to do" become acceptable to you? Or should friends, members of groups, supporters of teams or even students never be allowed to hang around in groups with nothing better to do, ever?

Don't we all need it sometimes, to just hang around with friends with nothing productive to do ? Guess you don't. I see it as better than watching TV tho.

Admit it, you're jealous of the loitering mopes and ne'er do wells.
