 So she stopped at her department store one day after school and told the salesgirl she wanted a nice, warm flannel nightgown. It doesn't have to be glamorous or pretty. I have a dresser drawer full of those, and if I wore all of them at once, I'd still freeze to death. The salesgirl laughed and showed Rhoda the heaviest flannel gown she had. That night, Rhoda slept warm and snug until morning. The next night, too.
