Was this wrong for my friend to do?

I know someone like this! Manipulative yet popular! It's sad but I think the best way to describe it is that we live in a dog eat dog world: competition. The facebook thing, that's just bow those b.itchy girls talk to one another, and it works. The high school thing, that was lame and I think wrong of her. I would say please distance yourself from her, if you're not going to be manipulative back. What a b.tch. Hope karma gets to her..
