Why do girls give guys dirty looks?

Well, There Are About a dozen possible reasons, but I'll give you three.

1. Very Tough Girls, all Have their sensitive side, so when they crush on guys, it tends to show up on their hard side, not all the time, though.

2. Some just plain bratty girls, will give everyone dirty stares, you get used to it.

3. Most Girls, Unlike Guys, Get the whole relationship and crushes, worked up in their mind. They "exaggerate. So when a guy they normally talk to hits on another chick, they get emotionally unstable.
