I have always told my son that he's going to meet a lot of new people every year of school. Some he won't like at all, some will be buddies for the school year, some will be, at best, a benevolent "familiar face" the following year and some will become close friends for years, some for life!
I've approached it as everyone has an equal right to be there and get an education and attend school. Everyone is equal. some people you "click" with and some you won't. Cultivate the friendships and ignore the BS!
