How to deal with/comeback rude comments?

You sound like you're in junior high, so I'm gonna tell you a lil secret...junior high girls are MEAN. High school girls are MEAN. And when you enter the work force, women there will be MEAN too. Girls can just be nasty, and its pretty much always because they feel insecure and its a way to feel better about themselves. Ignore them. When they say mean things, but on your snotty ***** face and walk away. Look thru them. And if all else fails, ask them SUPER sweetly if they feel any better about themselves now. Since, obviously, the must just be picking on you since they feel bad about their pathetic life. It gets better...most girls grow out of it...but put on your thick skin thru school.
