My 3-year-old son told the first story. In the evening, I asked my son to wash his hands when we got home, but he wouldn't like to. and suddenly said:"I have known a story today." I asked curiously：“what's the story?” "The borer."he answered. "What kind of borer?"I continued. Then he thought and said:"Some kids had meals but didn't brush their teeth. Borers went into their mouth and used the drill to drill a cavity on their mouth, then living there." "To live in their teeth?"I asked. "No,in their mouth."he corrected me immediatly . I knew his stubborn ,so I said:"Oh,my god.It's too terrible,isn't it? Did they feel any ache?" "Yes, very ache."he answered. "So what should they do?"I asked apprehensively. He stopped to think over a second and said:"They went to see a doctor. The doctor told them remember to brush their teeth after dinner." It is great to hear a story from my little boy. This is his first time to tell a whole story. And use the opportulity while I told him to wash his hands or borers will live in his belly. This time he accepted my advice and washed his hands fast . A useful story. Wonderful!
