See, you say that but you're quite rather wrong. It's 4:30 in the morning and I really want to sleep. I read a book and two different articles. Still awake.
and it's 4:30 in the morning.
Change that to 2:30 in the morning and we are in the same boat here!
Will try to sleep in another 15 minutes. At least this evening I will go straight to sleep because I AM going to school tomorrow...
