Extinguish vs. Trespass

One New York afternoon, when he came home from work, he found her sitting on the edge of the bed in that small room, staring at the pictures of herself on the opposite wall.

He did not want to trespass on her secrets. He simply wanted to extinguish the carnivals burning in her head.
