That's me. I first learned the joy of staying up late in the 9th grade...and I never looked back.
I learned to be a night owl from my mom. Can't remember ever going to bed early (on a regular basis), come to think of it...
I've always been a night owl, too. It's when I get my best energy.
Now that I'm working 7 days a week, 12 hours a day, I fall asleep before midnight out of pure exhaustion.
When I'm home and get those things called "weekends," I always manage to throw my body-closck out of whack real good on those Friday and Saturday nights.
