Please

DON'T
complain about others while you did not put in effort and help, while the rest tried their best.

DON'T
say how much you dislike a person before thinking from that person's point of view.
Not everyone same as you

DON'T
hide anything important that you think might jeopardise your good name from others.
People misunderstands sometimes.

DON'T
be a two-face.
don't like means don't like, confront that person, and solve the problem.
