Then the conversation digressed into a deep comparison of the different types of Dollar Stores. Who knew? (Who cared?). And, oh, they have their differences. What really concerned me was how educated my mother was in the world of Dollar Stores. And, it must be a generational fascination, because her roommate shared the same excitement. Her daughter and I just quietly listened in amusement as the two waxed on about locations, stock, and prices. (I learned that some Dollar Stores charged more than a dollar - these did not score well.) Consumer Reports is missing out on two limited area two experts here.
About that time we passed a Dollar Store on the highway. My mother's roommate's daughter commented, "Well, the continuity of civilization is now guaranteed. We can all sleep well tonight."
