Dear Peter,I am so glad to make friends with you.My name is Li Mei.
Yours,
Li Mei
I'm 13 years old. My hair is short. I'm tall and slim. I wear glasses. My favorite subject is Science. I think it's cool and can change our life. My classmates are friendly to me and often help me with my studies. Our teachers care about us and chat with us, discussing our problems. I like playing volleyball and I'm in the school volleyball team. I practice it every Friday. I also enjoy reading and have read many famous writers' works. I want to be a volleyball player; I hope my dream will come true.
Yours,
Li Mei
