I found an old box of my father's yesterday. It was really  to discover something about my father's life as a child. He once told me about his hobbies as a child. He wrote to people from all over the world, and they sent  letters back. As a result, he had a book of interesting stamps. People also  him things from different countries, such as a silk fan from China, a little model car from Germany and some kangaroo  from Australia. My father even kept the ticket from his first football match. The box made me think  my hobby. I would keep my old picture books and toys and I'm sure my children would like them in the future. That would be great fun.
