1. Not have to, but need. If I go to bed too late (say after 2 AM) I practically miss the whole following day.
2. Well, I don't usually stay up late, but when I do I'm either at a party, or working on a project which got more complicated than I expected, or involved in a late AIM conversation with someone from TPM, in most cases Ryan.
3. I prefer to be in bed by Midnight. It may be earlier if I'm too tired. Though when I get to sleep is a whole other story. It usually takes me between half an hour and two hours to fall asleep after I get in bed, depending on how fast my mind is spinning.
4. When I'm feeling good and I don't have anywhere to go in the morning (nor a good idea for a story), around 7:30 AM.
5. I actually checked it because it was one of the few topics I hadn't replied to, but I was expecting something about monsters or objects coming alive or something like that.
