It was very late at night on the eve of Memorial Day. She got on the subway  61  at the 34th Street Pennsylvania Station. I am still trying to remember  62 she managed to push herself  63 with a baby on her right arm, a traveling bag in her  64 hand and two children, a boy and a girl, about three and five years old,  65 after her. She was a nice looking white lady in her early twenties. At Nevins Street, Brooklyn, I saw her  66 to get off at the next station—Atlantic Avenue—  67 happened to be the place where I had to get off. Just  68  itwas a problem for her to get on, it was going to be a problem for her to get off the train  69 two small children to be  70  care of, a baby on her right arm and a medium-sized bag in her left hand.
