Y'know what's the worst? Being frustrated with yourself for being frustrated with yourself. If you (metaphorically) kick yourself for kicking yourself, that means that you're kicking with both legs, which implies, of necessity, that you are (metaphorically) falling on your ass.

In other news, I'm going to France and Germany for two weeks. Anyone else going to WYD? You can spot me easily: I'll be the grubby looking American, possibly wearing a space blanket as an impromptu hat.
