A year ago, I paid no attention to English idioms, though my teacher stressed the importance again and again. But soon, the importance of English idioms was shown in an amusing experience.

One day, I happened to meet an Englishman on the road, and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be astonished. Gently shaking his head, shrugging his shoulders, he said, "You don't say!" "You don't say!" I was puzzled. I thought, perhaps this is not an appropriate topic. "Well, I'd better change the topic." So I said to him, "Well, shall we talk about the Great Wall? By the way, have you ever been there?" "Certainly, everyone back home will laugh at me if I leave China without seeing it. It is magnificent." He was deep in thought when I began to talk like a tourist guide, "The Great Wall is one of the wonders in the world. We are very proud of it." Soon I was interrupted again by his words, "You don't say!" I couldn't help asking, "Why do you ask me not to talk about it?" "Well, I didn't request you to do so," he answered, greatly surprised. I said, "Didn't you say ‘You don't say!'?" Hearing this, the Englishman laughed to tears. He began to explain, " 'You don't say!' actually means 'Really!' It is an expression of surprise. Perhaps you don't pay attention to English idioms." Only then did I realize I had made a fool of myself. Since then I have been more careful with idiomatic expressions.
