On the contrary, time is flying, I gotta get going. I could be writing a masterpiece instead of complaining. I'm gonna make use of the time I have. Thanks for your support, Ms. Sue, it's been a pleasure talking to you. (:

Lol yeahh! But then I hand it in thinking it's an A+ and it turns out I get a B or something. You'd think I'd at least get an A- for effort...sigh.
