I'm glad to get the letter from you and want to tell you about my hobby. In fact I am also fond of collecting but not the coins. I collect watches. All my family members and friends know about it and they bring me watches from all over the world. There are 67 different types of watches in my collection. They all 
are different  in their shapes and colors. I don't have much free time for my hobby, but I try to find an hour or two a week to examine my collection and to find more information about the history of watches. My friends do not share my hobby but they like to bring me new watches for my collection.
