Dear Peter,
How are you? We go to school five days a week. I have a lot of friends in my school. And one of them
is from Canada. His name is Tom. I am learning English. He often teaches me English after school. He wants
to learn Chinese from me. So I help him with his Chinese. Sometimes we go out on Sundays. Please write to
me soon.
Love from
Harry
