As Mr Black is walking, he sees a man going to the chair, too. He thinks, "The man also wants to sit on the chair. I must go quickly."

So he walks faster. But the man also walks faster. Mr Black starts to run and the man starts to run, too. However, Mr Black is a little faster than the man. He gets to the chair first and sits on it. Just then, the man also reaches the chair. He raises a small board in his hands. It says, "Wet Paint."

Mr Black is walking in the park and he is very tired. He looks around and sees a chair in the distance. So he walks towards the chair.
