Good insights, Heidi. I've heard it said that disappointment is the negative difference between expectation and reality. You certainly see that here.
Roxburgh is excellent in pointing us to both the value and the danger of the past. If it is the controlling narrative, then there is no change. If we try to ignore it, it actually comes back around to influence the system in ways we don't expect -- a dynamic called "reflexifity," which modernity often tries to ignore.
