In a moment, the boy remembered. The next day, when the person wipe the table, readily draw a horizontal cross with a rag on the desktop, want to test the son does not recognize “a ” word. Who knows that boy can not recognize it at all. The scholar said: “This is the one that taught you yesterday.” “The boy widened his eyes and said in surprise:” Only after so long has the word grown so big? “”
