Nearly 2:30am over here, and the main reason I'm up is I missed my favourite show (Dr. G on Discovery Channel) and want to watch the rerun at 3AM. I don't have a VCR!
I love being up late sometimes, but I also love getting up early sometimes, so the two things clash from time to time and I pass out at like 9PM and sleep till noon the next day.
It definitely is one of the biggest advantages of being a 100% freelance worker, all I have to do is hit my deadlines and other than that I can stay up till whenever I want, and do whatever I want. I wanted to watch the Lidell vs. Jackson UFC matchup which was live at something like 5AM, and since it was already 2AM, I just stayed up till 5-6 AM to watch it. (And totally worth it too!)
Jam it back in, in the dark.
