At dusk, I sat in the classroom and listened to the English teacher explaining the test questions. When I was bored, I looked out the window. The sky in the west is full of red and yellow clouds, turning into golden colors. The sun that is about to set is sandwiched between two tall buildings, looking like a lone boat that has been plated with gold. But to the east is the blue sky, and the mountains in the distance are shaded into a deep gray tone, unusually like an uninhabited island. A deserted blur.
