bump up then lurk To be on the Safe Side 　　In a cinema during a performance one of the audience gets up, makes his way along the row of seats and goes out into the foyer. A few minutes later he returns and asks the man sitting at the head of the row:　　"Excuse me, was it your foot I stepped on when I was going out a moment ago?"　　" Yes, but it doesn't really matter. It didn't hurt at all."　　"Oh, no, it isn't that. I only want to make sure that this is my row."----------------------------------------------, , , , ,
