How tired was I last night? So much so, that I decided that, despite feeling wheelbarrows full of enthusiasm, I just had to get some sleep rather than go to the sociology department's karaoke night. How badly does karaoke need me? So much so, that when the Karaoke Kid heard I wasn't coming, they decided not to open last night, leaving scores of eager sociologists dismal in the snow. Sorry, all. I didn't realize I was so crucial for everyone's good time.
