Random Things

So you just got together with some friends. You had a good time, but it's time to go. So what do you do, you wave goodbye. The question is, why? I mean, what's the point in waving. So you stick your hand in the air, spread your fingers apart and move your hand frantically. Paints a funny picture when you think of it like that, doesn't it? It'd be funny if aliens came down and saw us doing that. "What is with these weird beings. They look like a bunch of idiots." I would really like to know where that started. So just think about that next time you see some friends and go to wave. It'll hit you...WHY AM I DOING THIS!?!?
