Everyone has his own inner world. Some are dreamy, colorful, beautiful... However, there is a gray castle living in my heart, which creates a shadow in my heart, like a walking zombie with its soul taken away. How can a person have no soul? So, I desperately wanted to turn this gray castle into color, but no matter how hard I tried, this shadow could not be erased. On the contrary, it always appeared in my dreams... During this winter vacation, I read "Childhood", one of the three autobiographical novels written by the famous former Soviet Russian writer Gorky.
