The case was long ago. At the time, I could hardly ride a bicycle. And, as a training, I went out of the house at night and drove on an empty road. It was smooth (mostly) and with a small deviation. The cold night wind swept my happy face. And then one day, when I ran decently under the hill, a guy in the roller coaster came to meet me. Just like me, in the middle of an empty road. And I panicked. Do you know what happens when people can’t get along the road? They walk in the same direction together. So we got out too. Only we did not stand still, but we went to meet each other at an inappropriate speed. They did not separate. In general, it turned out that I entered this guy, straight between the rolls. I am still shaking for him. He whispered that he was okay, and I, forgetting everything, moved home. And I don’t remember training there ever again.
