Mr. Green is a London taxi driver who love going to the theater. Last week his mother gave her two tickets for play. The tickets were for Sunday evening. Then Mr. Green read some reviews of the play, that said it was a terribly one! He wouldn't go to see the play that no one liked. So two hours after the beginning of the play, he left the tickets on the back seat of his taxi. He thought perhaps someone who wanted to see the play would take it. However ,when Mr. Green went back to home, the tickets were still there .On fact, there were four tickets on the seat. Someone had placed another pair of ticket on top of them!
