Once when I was sleeping at night, my roommate in the lower bunk came to push me and said it was insomnia. I said you had insomnia, so why did you push me? Then he jumped up and wanted to sleep with me. In winter, his hands are cold, and I am shivering with cold. I said you should come down. He said that all men warm each other and sleep together, and then we huddle together for one night.
