Dear Mike,

    Thanks for your family photo. This is a photo of my family. I have a happy family. There are five people in my family. They are my grandmother, my parents, my sister and I. The old woman is my grandmother. The man is my father. His name is David. He is a teacher. And what about the woman? She is my mother. Her name is Linda. She is very nice. Look at the girl. That's my sister. She is in a middle school (中学). Her name is Lucy. Do you know(知道) the boy? It's me.

Yours,

Tony
