Suppose you join a new club, or start a new job and meet a group of 15 to 20 new people all at once. How long would it take you to learn all of their names?
@futurebird My best "receipt" for being bad at remembering faces:
In one of the Marvel movies, there's a masked character. Halfway through the movie, he takes it off and the audience audibly gasps. I'm thinking, "Am I supposed to recognize this person?"
