Hobby is a favourite occupation of a person in his free time. I have many friends. They are very different and they have different kinds of hobbies.
One of my girl-friends, for example, likes to knit very much. Another girl-friend of mine spends all her free time sewing things: skirts, blouses, dresses. She makes it nicely and she always looks fine.
One of my friends likes to make everything with his own hands. He can repair an iron, a radio-set, or a tape-recorder. I think it's a very good hobby.
Many people are very fond of collecting. Some collect old coins, others collect post-cards. As for me, my hobby is collecting stamps. Now I have 5 albums full of stamps.
I like to sit at the table in the evening and arrange new stamps in the albums or just look through the stamps. Each stamp has a story to tell about distant countries and new people.
I see pictures of people, birds and animals which I have never seen. Kings and presidents pass before my eyes and I can follow the history of whole nations.
My hobby is not only wonderful but is also very useful.
