Embarrassment means the moment mattered to you, and things that mattered have detail attached. That detail is what makes a story funny rather than merely reported, since comedy runs on specifics and stakes. Time also does most of the work for you: the thing that was unbearable at fourteen is simply material now.

Write down three things that made you want to disappear, with the details you usually skip. Tell one of them to a friend as a story rather than a confession. Watch where they laugh, because that is the part that was never really about you.
