Years ago, when Dad moved to the US, I had to go to school in New York. I was worried. How could I, an 8-year-old girl from , make friends in America? On my first day at Anna Silver School, I met Miss Alice Green, my class . She spoke to me slowly and to get me used to her American accent. When she discovered that I drawing, she took me as the teacher. Miss Green made sure that I fit into (适应) her class easily, and before I knew it, I was already having fun, just as other schoolgirls were. When Dad was sent back to India, I had to Anna Silver School. I was again. Miss Green had planned to take us students for a trip, but I had to say goodbye to them now. So, with a heart, I left my school and the US. Back in India, I received a package one day. It was Miss Green and my classmates. They had written me a letter each, me about the fishing trip. Miss Green said she me very much. With her good wishes, she added: “Keep up with your drawing, you love it so much.” I’m very to Miss Green. She not only made a shy little feel at home in a faraway country, but also taught me and my classmates to understand the importance of being kind to others at an early age.
