      Christmas Day was coming.I was just a kid then，and my elder sister told me there was no Santa Claus.I fled to my grandma's house because she would be straight with me.I knew Grandma always told me the truth.Grandma was at home，and I told her everything.She was ready for me. "No Santa Claus？" she shouted. "Ridiculous!Don't believe it.That rumour has been going around for years，and it makes me mad."
      "Now，put on your coat，and let's go."
      "Go where，grandma？" I asked. "Where" turned out to be Kerby's General Store，the one store in the town that had a little bit of just about everything.As we walked through its doors，Grandma handed me ten dollars. "Take this money，" she said， "and buy something for someone who needs it.I'll wait for you in the car." Then she turned and walked out of Kerby's.
      I was only eight years old.I'd often gone shopping with my mother，but never had I shopped for anything all by myself.The store seemed big and crowded，full of people competing to finish their Christmas shopping.For a few moments I just stood there，confused，holding that ten-dollar bill and wondering what to buy and who to buy it for.I suddenly thought of Bobby Decker，who was a kid with bad breath and messy hair.He sat right behind me in Mrs Pollock's grade-two class.Bobby Decker didn't have a coat.I knew that because he never went out for recess（课间休息）during the winter.His mother always wrote a note，telling the teacher that he had a cough，but we kids knew that Bobby Decker didn't have a cough，and he didn't have a coat.I would buy Bobby Decker a coat!I settled on a red one，which looked really warm，and he would like that.
      "Is this a Christmas present for someone？" the lady behind the counter asked kindly，as I laid my ten dollars down. "Yes."
      The nice lady smiled at me，put the coat in a bag and wished me a merry Christmas.
  Paragraph 1：
      That evening，Grandma helped me wrap the coat in Christmas paper._______
  Paragraph 2：
      Grandma and I waited breathlessly for Bobby Decker's front door to open and finally it opened._______
