I am a night person, with few friends. So I am stuck with no one to talk to at 5 AM.
However, I guess it's a lie. I do get tired eventually. I went to class one time first semester with 0 sleep. It was an 8AM class. I was up at 6 when I realized I had to goto class, and figured I would not just goto sleep for an hour. Eventually sleep just kicks you in the ass, and I nearly fell down the stairs passing out.
Agreed. My roommate my first year of college would always greet me with an overly chipper "good morning!!!" and a big dumb grin at like 7 in the morning. This was especially annoying on Saturdays and Sundays when I was only getting up to go to the bathroom and then go back to sleep for a few more hours.
