From Bonnie Angelo’s interview on Booknotes:

“When Ronald Reagan heard George Bush telling about how the chauffeurs would race to take the kids to school, Reagan just would kind of roll his eyes, because in his really poor, poor growing up years, he'd walk through, you know, two feet of snow, whatever length of distance it was to school. Nobody took him. He couldn't even, you know, ride a bus. So their lives were so different.“
