People pretending to be friends

I think people like you've mention is desperately asking for attention. They want to belong and be accepted by a group of people. Maybe she finds your company fun, open and friendly and she likes to be in your group. Maybe, she is just conscious to be alone. She might become annoying in a sense that she is just pretending. If you and your friends are considerate enough and understands her, you can help her in her emotion needs so that she can practice to be true.

yeah, ive met some of them... when i was in college, and at work... its true you can really feel it, they flatter too much sometimes. i just dont like those kind of people... i may not be that friendly at first, it takes a lot before i get to start talking, so whenever i meet some of those that talks a lot even when you've just met them, i kind of become suspicious... and im careful in choosing friends too, even those that you think are your friends for a long time are also just pretending because they can get something from you, you only know it when it happens.
