You are so not mean, that you're getting walked all over by anyone who feels like pushing you around. Your easygoing attitude is commendable, but there is a point where you have to draw the line and get a spine. Don't let the mean girls of this world make you their doormat. Stand up for yourself, stop apologizing when it's not your fault, and realize that you're good enough to make your opinions heard and to expect others to treat you with respect.
Good for you! You manage to strike a sensible balance between standing up for yourself, and being nice to others. You're a friendly and well-liked person who genuinely enjoys getting to know other people. However, when someone is rude or pushes you down, you're not above pushing back. And that's good - you teach others that you expect to be treated with respect.
You are one mean chick! While your self-confidence is enviable, it verges on egomania. You might be popular, but that's only because people are scared of you. Secretly, many people have bad feelings about you and your mean girl act could end up backfiring on you someday. You are probably also annoyed most of the time. News alert: Other people do have feelings!
