The "I can definitely see that" part of my comment was because I really can. I work well at that time of day and there are times when I would love to just keep cranking away. Maybe some of them, like btilly says, get there late. I could see that working: spend some time with the kid(s) in the morning and then work later.

Maybe they're not morning people? I sometimes get on a bad cycle of work late, stay up late, sleep in, and get into work at 11 the next day. It's not because anyone asked me to keep this schedule.
