I Often Wonder...

Maybe this only applies to me. But you know when you have friends--or rather "part-time friends" as I like to call them? That group of friends that's nice to you and talks to you [usually when they want something] but never really invites you to out-of-school activities or much less the lunch table? You know when you see them be nice to people and all buddy-buddy, and then talk about them behind their backs? I often wonder if they do the same to me...
