Sometimes I think it just comes down to being selfish and them thinking they are getting one over on you and getting ahead. For some reason people like that just tell themselves life is a game and that everyone cheats once in a while to get ahead and then they think it's all ok.
and they just want the benefits of being in two worlds. act one way with some people, act different with others being all crazy. but by doing that even though you think everyone wins, you already lost your true friends and people in the truth.
