When I was a child I liked to do silly things. Once, when I was in the village, I walked around countryside. And later I saw a cow. I decaded to get on it. I didn't know why I wanted it, maybe because I thought that it would be funny. I knew it was dangerous, but I did it. The cow was running very fast. My hair was waving in the wind. This was spectacular. I don't remember how I got off, but after that happening I dedided - I will became equestrian.

After holidays, when I arrived to home from village, I started going to equestrian club. At first it was hard for me, but over time my skills was becoming better and better. Nowadays, I'm very good in horse riding.
