There's something about those moments where one comes to feel one has made a mistake, and vows to learn from excessive dismissiveness (or similar) in some situation, and one goes back to check up on exactly how badly one in fact screwed up, only to find that one was right all along. What one does in that circumstance is very defining.
At the advice of a friend, I got some Claratin last night, and took it. Does it work? "Sort Of" seems to be the best answer.
