Actually, let me make it easier for you: You go see PennyO in her show. You don't think she's very good. You go backstage or you talk later. Do you say nothing? Especially if she asks? I think you know the answer. Or you see Ben's ever-lovin' Ant in a show and he and Ben are together after - do you say nothing? Is that what you do? And if they ask "Did you like it?" you say nothing? Or you say, "Gee, I really didn't - I didn't think Ant was good and the show was kind of awful." Is that it? Because there's no difference here, except it's a chat board. Feelings are feelings, I'm afraid. If the above scenarios were me, I'd say "Good job" and be done with it, because that's the friendly and nice thing to do and it's kind of painless to do it. To be silent would speak louder than if I said "Hated it", which was Mr. Sondheim's point.
