A hobby is something that people do for pleasure in their free time. People have a lot of hobbies, but tastes differ, of course. Some individuals are fond of collecting stamps, post-cards, labels. These are the most common cases, I believe. By the way, they cost a pretty penny, they really do. Stamps are very expensive nowadays, to say nothing about books. Books are not deficit items any more, but prices! When you are keen on reading, you don't think about money. Who doubts the usefulness of reading? Nobody does.
Of course, there can be more exotic occupations like, say, taming cats, dogs, rabbits, mice. We can mock at the men when their hobbies are embroidery and sewing and at women when playing football becomes their hobby. But they think differently. Their hobbies help them be full of vigour and vitality.
Stamp collecting or playing chess enrich our knowledge in different fields. Collecting photos of favourite actors or musicians also enables a person to keep abreast of the latest cultural news.
Rich people all over the world can afford collecting paintings, coins, icons, cars. Elizabeth Taylor, for example, collected diamonds. Leonid Ilich Brezhnev collected cars. Our tastes are more prosaic, of course. If I had a lot of money, I'd devote all my spare time to travelling. I wish I could go abroad, to Italy, for example. And I want very much to visit the United Kingdom, not only for sightseeing, but stay there for a while and see how they live there and how they teach students.
As for my dislikes, I don't like many things. I don't like porridge and hot milk; don't like to be laughed at… But to put it seriously I don't like to be bored and don't like selfish people.
