1. Insecureness.
2 Always waiting till it's too late to tell you what is bothering them.
3. When they get their periods

. All the mood swings, insecureness, and bitchiness resulting.
4. Girls(esp beautiful girls) who dress really sexy or slutty then give you a cold glare when they see you admiring/staring at them.
5. Time to get ready. My gawd it always takes girls forever to get ready.
6. Oh yeah and head games.
7. Girls who wear grandma panties *shudders* why?
