Meh?

I fell off my skateboard again yesterday. Right into the road... again. Different spot though. Hit a rock this time so I ended up rolling rather than sliding on the ground. I think my brain has started turning itself off any opportunity it gets that I'm not concentrating. Case in point, I fell asleep during my graphics class the other day and I seem to zone out a lot in my software engineering class. When I'm in my OS class, though, I'm all bright-eyed and bushy-tailed. Funny thing is, my graphics class is only 5 minutes after my OS class. Bizarre...
