Different people have different hobbies. Some like raising flowers，others like building model ships. I like collecting stamps.
My father works in a big company. He always goes abroad.Two years ago, when he was working abroad，he sent home a letter with a beautiful stamp on the envelope. I liked the stamp very much.Since then I always ask my father to send me different stamps from different countries.
Now I have more than a thousand stamps. From these stamps I can learn a lot. When I look through these beautiful stamps,I feel relaxed and happy.
