In your English class, you are asked to describe the following picture and explain to your classmates how you understand it.
One possible version:
In the picture, a man and a woman are looking at the same thing — a coin. But they have different ideas of the coin. What the man knows is the front side of the coin and the woman knows is the back side of the coin.
From this picture we can know the reason why people have different ideas about the same thing. They are looking at it from different directions. So next time when your friends' ideas are different from yours, don't get angry. Try to think about the things from their standpoints. Maybe you can see another picture.
