I’ll start:
Obligatory soliloquy stating how I have been uncharacteristically morose for days, and am only just now feeling bouyant again and, possibly, even slightly impish.
Halfhearted grumbling about how now, ironically, everyone else seems to be grumpy.
Sudden expression of resistance to the idea of being staid and boring, even if it is 9:30 on a thursday night.
