Sunday night I stayed up...well I went to bed at 4:00 Monday morning

I was working on strategy, and having an interesting chat with Jim, Wetzel and Cory...
For some reason I have a hard time getting to bed. Freshman year I was in bed by 9:30, sophomore year I was in bed by 10 or 10:30, last year I was in bed no later than 11. Now sometimes im up till Midnight....usually I don't even have homework. I just can't motivate myself to go to bed.
My paernts call me Owl or Nighthawk because they always wonder how I can be up late and still be up at a decent hour in the morning when there is no school
