Her doctor had told Julian's mother that she must lose twenty pounds on account of her blood pressure, so on Wednesday nights Julian had to take her downtown on the bus for a reducing class at the Y. The reducing class was designed, for working girls over fifty, who weighed from 165 to 200 pounds. His mother was one of the slimmer ones, but she said ladies did not tell their age or weight. She would not ride the buses by herself at night and because the reducing class was one of her few pleasures, necessary for her health, and free, she said Julian could at least put himself out to take her, considering all she did for him. Julian did not like to consider all she did for him, but every Wednesday night he braced himself and took her.
