Good: Discovering that trading massages with Rowdy really is a "you mean I can have candy with every meal?" situation. (Except without the part where that would be kind of gross after two or three meals, and massages are perpetually awesome.)
Abruptly coming down with a massive fever on the way to a play party. I really really really wanted to go, I was actually at a train terminal halfway there, and *WHAM* my body informs me that I'll be lucky to stay upright. (This "wham" later clocked in at 103.8F. Damn.) I wussed out and went home alone. Ugh.
