My friend sent a photo of the window closed, and it was all black outside the window. What do residents want to express when they turn on the lights? Ask for a classic sentence or poem.

I feel lonely from the picture, because the window is sealed, which makes people feel isolated from the outside world. This shot is taken from the bottom up, which usually expresses what I have been longing for. I saw someone with the light on outside. Although there are no bright lights, the residents who turn on the lights in the night sky are still warm. Express the feeling of wanting to go out or being lonely.
