Famous quotes containing the word form:
“Shopping seemed to take an entirely too important place in women’s lives. You never saw men milling around in men’s departments. They made quick work of it. I used to wonder if shopping was a form of escape for women who had no worthwhile interests.”
—Mary Barnett Gilson (1877–?)
