Would the real Liza please come back?

Normally, during finals, I attempt to remain at least mostly cheerful. If that means I have to fake it every once in a while, that's fine with me. If it means that less cheerful people want to smack me upside the head, that's fine too. However, this latest round of finals seems to have brought out some sort of cranky, bitter, and slightly alcoholic alter ego. So, with that, I'll be back after finals are over next Tuesday, or as soon as I regain my former disposition, whichever comes first.
Cheers,
Liza
