“Once upon a time,” that is the way fairy tales start. It conjures up images of a better time. Fairy tales always start off well, then things fall apart, but all ends well and “They lived happily ever after.”
I think a lot of people are living with “once upon a time” syndrome. We idolize the past and forget that the good old days weren’t all that good. We look back to some golden era in our history and want to regain its imagined glory.
