I am NOT a morning person. In any sense of the word. I would rather sleep in til 10 am and stay up late. It is just what feels better for my body. To be honest, on vacation I can literally switch my sleep wake cycle with no problem at all. When I was a kid my dad would tell me to smile every morning when I got up. Given that I had to get up between 6 and 6:30 to go to school, I was not a happy camper. It drove me nuts every day to have to listen to him say it. I'm so glad I don't live with them any more because this one thing was enough to drive me up the wall.
