Everywhere you go no matter in what profession or year of schooling, you're going to get people who bother you, people who you like and people who you're neutral with. Don't give up for that reason because if you do consider that even more, then do remember, if you hop to another profession or major, you'll find the same issue there also. Best to just deal with it, ignore those who bother you and simply move on. If you fuss over those who bother you then you'll wind up going nowhere.
