In the third story, Doreene and Evelyn's mother collected personal property from people who owned them money before they left for Oklahoma.
THey did not gave other people money to pay their overdue grocery bills as they didnt have the money; they did not help her brother change a flat tire on a dark night as that didn't happen before their mother left for Oklahoma; and they did not buy a Model T truck as again, they needed money. Since they needed money and they went to the people who owned them money but didn't get any, so they collected these people's personal properties instead.
