You spend a weekend replaying a social stumble that everyone else forgot within the hour.
Thomas Gilovich and his colleagues at Cornell had people wear an embarrassing T-shirt into a room, then estimate how many others had noticed it. Their estimates were roughly twice the actual number.
You feel your own nervousness and embarrassment in full. Other people see a brief impression, often while they're already focused on their own version of the same problem.

@Daojoan it’s a healthy thing to remember, that people notice you far less than you think they do (it can be a hell of an ego killer, though - ‘what, they’re not paying full attention to me?!’).
