.... come home from dinner-and-a-movie extremely tired around 11
.... login to World of Warcraft "just to check to see if that item you were selling finally sold."
.... see someone online that you hadn't talked to in a while
.... realize that it's quarter-to-five in the morning and you're still not in bed
Ah well, I'll sleep really late, and be really awake for poker tonight.
Hey, that's not fair - I don't get to sleep all day!
Thank goodness I drink coffee like a fiend. :-)
