There are two college-age persons who live at our house and call me "Mom," and they are reasonably well-informed about American history, sociology, economics, and other aspects of our culture. Yet they have one blind spot. They believe that the time of their parent's youth is known as the Olden Days; everyone who lived then was a righteous, thrifty, ambitious "square," and certainly college life bore no resemblance to the enlightened way they are living it now.
