I am all ears 洗耳恭听

　　One day, we hired a carpenter to repair our house. I dwelt on (详细讲述）all the details that needed repairing to him. then I asked him, "Are you clear? Can you remember all that?" "Yes!" the carpenter replied. "I am all ears!" I felt puzzled and did not know what he meant. Later my eldest son explained to me that he meant, "I am listening attentively!".
