article: Dear Alice,
  I just received your letter. And I was very surprised to know that you decided to drop out of school and wanted to be a model .
  Being a model for a living is not easy. In fact, a famous person like me has a lot of problems that you couldn't see. I can't eat what I like, even though I'm very hungry. Keeping thin makes me look more beautiful on the stage because no one would like to see a heavy model.
  Besides, I have to wear a heavy coat in the hot sun, in a swimming suit in the cold air. And practicing walking nicely every day is tiring for me.
  You might say I made much money from modeling. But my dear niece  , you have to know that money is nothing, knowledge is everything. School is important and everyone should go to school for a certain period of time. The longer they stay at school, the better they will be. Very often, I hope I can give up my job and continue my studies at school. But it is very difficult for me to go back to school again. I am too old to go back to school now.
  You are a pretty young girl with a bright future. You only have one year to finish your studies in high school. A year is really short. Please do consider my words carefully before you decide. Of course, there is only one thing I care about, and that is your happiness.
  Love,
  Emma
