I used to be able to sleep in all day long. I'd go to bed late, and then wake up fresh at the crack 'o noon. I could recharge my batteries in one friggin 24 hour period.
Last night I go to bed at eleven, and I purposely leave the alarm off. No damn alarm today. Nope, but there I was awake at 6:30 AM, bright eyed and bushy-tailed. So I gave up and started some coffee.
I'm turning into my father.
