Pretenders????? are they hateful?? why??

Pretenders?It's really disappointing to know that there are people who pretend. It is like some sort of mental coping mechanism. Like delusions of grandeur. If I happen to know someone like that , I will confront him and tell him, right on his face, that what he is doing is wrong. He should realize that peaple around him are not real friends, in fact they are pretending too.
