And I never forget the first time I received the cheering in my life. Flowers arrived 39 my brothers and sister. My husband gave me silk roses. The reporters came with 40 and recorders and lots of questions. There were tears and hugs and congratulations. Sometimes, I sit down and 41 the tape of my gaduation speech.
