ответ:I have one hobby.

My hobby is swimming.

I enjoy it very much.

It is not expensive.

I do it in a company with my friend.

This hobby is done inside the swimming pool and also outside during my summer holidays.

I love it because it is relaxing.

The best thing about my hobby is that I feel it's good for my health.

But I don't like that the way to the pool takes much time.
