I'm not, and never will be good enough for any of them.
Who told you that you aren't good enough?
No one, I just know. I can tell by their actions, the way they never start the conversation unless they want something like the homework answers. The way they're always flirting with another girl, and I'm just the "backup" when that girl happens to not be there. I'm that friend who never gets a person's number when the whole other group did; and if I do get their number, we never talk anyway. Actions speak louder than words. I don't need anyone to tell me that I'm not good enough when I can see that I'm not with my own eyes.
