My wife was playing her first neutral character (a bard--she usually plays paladins or clerics) in a recent campaign. Several farmers in town had recently lost cows to an owlbear. The party bought some cows and set a trap for the owlbear, managing to slay it after a tough battle in which the cleric went down bleeding. With the owlbear dead, the party didn't really have much need for the cows, and glancing over, I could see my wife silently thinking to herself about giving the party's cows to the farmers who had lost their cows (she wasn't saying a word, I can just read her pretty well). As the rest of the players are still excitedly talking back and forth about the owlbear fight, I see a look of disappointed realization cross her face as she interrupts the ongoing conversation by loudly blurting out:
"Oh crap, I'm not good!"
All the rest of the players immediately go silent and just stare at her, trying to puzzle out exactly what possessed my wife to say that. It has since become one of my group's favorite quoted lines, repeated at least once per session.
