Why do girls trip about little things?

Cause a woman relies on a man to feel good about herself. While a man generally focuses on what he did (I built this, I lifted that, I accomplished and so forth) a woman focuses on man (I.e. he bought me this, he took me there, I got him to do this). The more a woman can get a man to do, the better she feels about herself. No matter how little it is, if she can get her way, the better she feels about herself. This explains why "bitches be trippin"
