It's one hour till my first breakout session. There isn't time enough to start anything, like actual work from the office at home. It's pointless to worry about my session - I'm well prepared for it anyway but if I wasn't, there isn't time to add a demo or change the deck or anything like that. I just have to sit and wait. It's one of my poorest skills. So I sit and stew instead, which is nowhere near the same thing.
But if you're reading this, and it's not 4:45 yet, come on to S230C and learn about MFC Updates. Why not?
