When I was young, not only my mother took care of me but also my father brought me up similarly to my mother, who could do many things my mother could not. He protected me from danger. In the past fifteen years, I fell into the river. At that moment, I could not swim. I sank down deeply into the river. I thought that I could not survive. Then, my father jumped into the river to save me. This event makes me realized that hero really exists in this world.
