No teen wants to be walked all over or taken advantage of. We don't want to feel weak or like we're a push over. But, we are afraid if we try to be kind or give people the benefit of the doubt, then they'll step all over us.
However, in order to stop feeling like we are being walked on, other people don't have to do anything. We have to do something. Two things, actually. Change our view and enact boundaries. Doing those two things is the difference between being a door and a doormat.
