I was reminded recently of a guy I've encountered a couple of times who doesn't seem to have learned everything he needed to know in kindergarten--seems to have skipped sharing. He's a great singer with an unusual repertoire, very outgoing and not a pain to listen to at all--but once he gets the floor, he goes on way too long. Because he has vision problems, he does not pick up on any subtle visual cues.

On the plus side, one of our regulars who is also a noted floor-hog just did the opposite. Taking his turn in a crowded session with limited time, he chose what is normally a rather long song, but announced that he was doing the "short" version and left out two-thirds of the verses. Seems odd not to have just picked something shorter, but I guess he was set on that one. Anyway, his increased sensitivity was encouraging.
