Never sacrifice your class to get even with someone who has none. Let them have the gutter. You take the high road.

I try to not stay with people that consciously try to bring the worst of myself to the surface. I won't show others the worst of me just for equality.
I can be my worst enemy and surfacing my worst part can be bad for myself and for others
I try to induce others to show their best and I would better be surrounded by others that want to know the best of me
