The show was on.It is was dark in the cinema.One of the audience got up,moving along the row of seats and went to the smoking-room.A few minutes later he cameback and asked the man sitting at the head of the row.
"Excuse me, was it your foot that I stepped on when I went out a moment ago?""Yes,"the man said,"but it doesn't matter.It didn't hurt at all."
"Oh,I know you would forgive me , I ask only because I want to make sure if this is my row."
