(A) F: I am afraid I did not quite catch what you were saying. Please repeat it. (B) F: So your mom taught you to write business plans. That's a quite new way to learn poetry. (C) F: Oh, your mom asked you to read from very young. Now I understand why you have written so many beautiful pieces of poetry before. (D) F: I see. You were required by your mom to read from early childhood, so you gained a good grasp of English and a good taste of words.
