Last week, I taught how to ride a bike. At first, I couldn’t keep my balance, so my father seizes the back of the bike. A next day, he said to me, “I think you can ride the bike by itself.” Though I had told him that I needed his help, but he loosened his hands. I was scaring, and I fell off the bike. He said a few words of encourage to me and I tried again. This time, he secret loosened his hands and didn’t tell me. He just ran with me with his hands on my bike. Moment later, I felt the bike shaking, but I didn’t fall off. When I stopped the bike, my father was looking at me with a smile.
