I found five other students who lived in other *dormitories who also had no way of getting home and invited them to dinner. It never occurred to me to ask someone if I could stay in my room. It was my room, after all. But on Wednesday night, when the heating in the dormitory was turned down to whatever temperature was needed to keep water from freezing in the pipes, I wondered if maybe I'd been expected to leave along with all the other girls. Too late now. The office was closed until Monday morning. In those days, before cell phones and the internet, such problems were solved not by changing my coat. the situation but by changing yourself. I put on another sweater and (3) I suppose before I went to college I had been very modestly helpful to m mother on Thanksgiving.
