求一篇 letter to PEN PAL 作文

My pen pal is an American boy。 He has a family of five。 His mother is a math teacher and his father is an engineer。 He's in the sixth grade like me and we have so many topic to chat about。 I have learned an interesting fact that when I am falling asleep in the evening, he is about to take the morning bus to go to school。 Do you know why? Because he's in the other side of the world!
