My father and his friend played tennis whenever they have some free time(Перевод:Мой папа и его друг играют в теннис ... они имеют акцию)

Many people have hobbies. They make our life more interesting. A hobby is what people like to do when they have free time. 
My hobby is playing computer games. Both grown-ups and children are fond of it now. It has become one of the most popular hobbies nowadays. I think that playing with a computer is very interesting. It is not only "wasting time" as some people say. 
Computer games make us to think things over properly, they widen and develop our mind and imagination. I have a good collection of different games and when I have some free time I play them with great pleasure. 
Some of my friends have the same hobby and we like to play together.
