What has Facebook taught you?

For me I learned that people are Not what I thought they were. All they care about are themselves while ignoring me. People are so full of themselves, so selfish and vain its Sickening. Its all about them. People need to get over themselves. My grandmother recently died and Only 1 relative and 2 friends said a kind word to me on my wall. Facebook shows peoples True Colors. The more I find out about people the more I dislike them. Thinking of deleting facebook soon. I don't need to read about another whatever I was not invited to. But I probably would not go anyway since I have better more fun things to do. and They are boring because its all about Them.
