Why?

Why is it that everyone has to act a certain way, dress a certain way, or talk a certain? Why is it that people are afraid to show there true colours? Why do people act one way around certain friends then differently around others? Why must everyone try so hard to fit in? Why do we try to hid what we are good at so people accept us? Why do smart people act dumb? Why do nice people have to ignore you and be rude? Why cant we all just be ourselves in any situation? Why do we plaster ourselves with makeup and hid the true beauty? Why is it that we change our belief's so we don't get made fun of? Why must we hid our true feeling's? Why do people spread rumor's instead of just getting the truth? Why cant we all just get along? Why don't we make a difference? WHY?
