During the week I am a morning person because I have to get up at 5:30ish for work. But on the weekends I stay up later and sleep in a bit later (8ish). When I get up, I'm up! I don't need coffee or anything to get me going. My alarm goes off and there's no hitting the snooze button for me. I think I became this way because when I lived at home with my parents I had my alarm clock across the room so I had to get out of bed to turn it off. Then I would just stay up and begin my day.
Bruce is the exact opposite of me.
