About how much time separates the third part of the Memoir from the second part in Traveling From Just As I Thought

The third part has been separated from the second part since the fifty years.

Explanation:

Travelling, the short story by Grace Paley, is about when Paley's mom and sister rode the transport during the twenties and wouldn't climb from the rear of the transport, in spite of the way that "'It's for them'– waving behind him at the Negroes, among whom they were presently sitting."

Paley associates this occasion with a minute in her own life when she offered her own seat on a transport to a dark lady holding her infant, and at last wound up holding the lady's kid for her so as to allow her to rest, notwithstanding the way that other white individuals on the transport couldn't help contradicting such a game-plan. The piece is superficially about the bigotry of the time, not sudden from Paley, who went through the greater part of her time on earth as an extremist, but at the same time is about the occasions that stay with us and shape us and about the associations that exist between individuals from a family.
