What is the name of the emotion that you feel when you accidentally make a mistake? Such as when you clumsily drop a bowl and it shatters? In the Simpsons, Homer says "D'oh!" when this sort of thing happens.
I don't think it's "regret", because you didn't do it on purpose. "Chagrined", perhaps? Is there a more common word for this emotion?
D'oh
covers a vast range of emotions.
