It was a weekend night. The dark clouds outside the window darken the sky, and the night covers the eyes of rain. Suddenly there was a thunder, and a flash of lightning scattered the darkness. As if it were a signal, the river flow into the world from heaven. In the starless night, the rain became the main character, dancing on the window glass. I opened the curtain and saw the distant light shimmering, lonely but softly in the falling rain. Turns out the rain is not heavy, but the wind makes it tense.
