I'll try to stay on topic. Everyone has something from the past to reminisce about. Even young adults in their twenties and thirties, slaving away in an office or on an assembly line five days a week, remember their youth when they were in school (or at least recess). There are some who are old enough can remember a less complicated, less materialistic time. If you were poor, you didn't know it because the Jones' had not yet gotten into conspicuous consumption. IMHO, everyone, even those who have been subject to discrimination, have their good ole days.
Is it trite to refer to the good ole days? Perhaps, but it can relieve some stress and, on rare occassion, may be enlightening for the hearers.
Fair warning: If you don't want to hear reminiscences about the 1940s, don't read the following.
Cokes 5¢ (the cola, not the white powder), Hershey bars 5¢, Saturday afternoon movies 12¢ (six cartoons, newsreel, serial adventure, and two main feature movies; if you liked the show, you could stay and see it again; our parents used the time to conceive our little siblings). Now, those were the times. Of course, our parents had grown up during the Great Depression; they may have not had any good ole days. Their frugal habits didn't register with us kids until years later when we began to accumulate stuff.
