I registered just to comment on this one. I knew everyone had embarrassment flashbacks, some as constantly as me, but I didn't know everyone made audible sounds at the event! I tend to unconsciously repeat part of a phrase I said at the time, or say the thing I wish I'd said at the time, continuing the conversation with myself. Alternatively, I sometimes squint my eyes in a weird way as though I'm trying to pinch off my brain from fulling living out the memory.

Let's see, example moments:

• Weeks ago, my wife's coworker expressed some questionable opinions about faith healing and whatnot. I said "Riiiiiight," in the most belittling, jerky way possible, and turned around to continue the conversation, only to see she'd walked out the door.

• Getting a "Look, I'm not that into you" email from one (actually not-that-significant) love interest in college

• Interesting variation: I had a really good friend and coworker, years ago, who I think grew to like and respect me less over the course of our 2nd year working together. There's plenty of distinct memories of my individual mistakes and decisions that led to this, but, I get the feeling any time I think about that PERSON, who never did anything wrong. I associate them with judging me for my multiple gaffes.
