A letter to Hero School Weekly

November 13 Dear Izzy, I’m going to New York to study next month. This means I will leave my friends at the end of the year. I worry about making new friends at my new school. Maria is my best friend. I think I will miss her. I hope she can find new friends but still keep in touch (保持联系) with me. I’ve known her for 8 years. But I really don’t want to leave my friends. What should I do? Sincerely, Cindy
