Who knows?

I've been looking over the last few days and, like any situation, it turns out that people you thought you knew are completely different than they lead you to believe.       A really creepy guy can be really sweet and your best friend can be a total bitch.    Every day, people you know tell you a lie.   It can be a white lie, to protect someones feelings, or it can be a big lie that means a lot to you.   And every day, we think we know so much.    Look around you.  Tell me, what do you see?  Now tell me, how much of it is real?
