Dear stranger:
Hello, I am Lin Lin, a primary school student who comes from a flower garden. I am seven years old this year. My teacher gave us an assignment to write letters. Can I make friends with you?
Dear Lin:
Hello, my name is Timothy Drake. I am eight years old and I am from Gotham City. It is a pleasure to meet you and to be friends with you.
Intention: No matter what, you should write more letters
