Tom Norris was an acquaintance of Beverly Crusher during her youth. She went on one date with him, which abruptly ended with the question "Is that a beard or is your face dirty?" Beverly later realized that she had really hurt him, and from that point on she was more conscious of others' feelings.
Jean-Luc Picard referenced the incident, while he temporarily had the ability to read Crusher's thoughts in 2370. (TNG: "Attached")
