There are some people you like and there are some people you don't like. Though the latter may outweigh the former you should try and be happy and stick around for them. Because who knows, maybe they are only sticking around for you.
Who's sticking around for us? The latter, or the former? I'd want the people I like to stick around, but not the ones I don't like, because I'll obviously not like them for a reason, and therefore don't want them to stick around because of me.
