SETTING: An elevator in a central London midrise. shadowdaddy and webcowgirl, who work on the top floor, grin at each other as they watch the doors of their otherwise empty car close. Suddenly a handbag is thrust inbetween the nearly-shut doors. They re-open, and a middle aged lawyer walks in. As this discussion goes on, three more people get on the elevator, pressing various buttons.
webcowgirl: How rude! Was that necessary? Lawyer (looking shocked, sort of): Well, yes, or the doors would have shut! webcowgirl: That is the point!
(See, the thing is, other elevators will come. This was not the last one.)
