At first, I thought that maybe I could give them an F... but after a while, I reconsidered my decission, and thought that U might be more appropriate...or maybe C...hmm or K. Then my girlfriend came in and siad that it is wrong, and told me to, to give you an Y. When she left, I changed it to O.... but since I don't have a girlfriend and I just made it up, Im giving you a final U.
