I am Ken. Three years ago, I saw a beautiful stamp on an envelope. The letter was from my father's friend. I loved the stamp very much. My father let me keep it and that was the first stamp I had. Now I have about two hundred stamps. I always go to the post office to buy stamps at the weekend. Sometimes I use my pocket money to buy some stamps, but I can't buy the most beautiful ones. They are very dear. Now I have 10 pounds. It is just enough to buy a new stamp with a panda. So I get ready to go to the post office near my house.-w4w.c.^4r
