I expected
in my youth
a natural ending.
You railed against presumption.
Never!
Always!
Hyperbole spun us out,
Now our orbits can’t intersect.
I was okay with that,
until I wasn’t.
We’re not supposed to break promises,
even irrelevant ones.
Curse nostalgia.
Shawn L. Bird 
Nostalgia is an appropriate term, considering changes in values and assumptions over time. Some weather the changes. To others, they’re unacceptable. Still others recognize them from both sides, but not many can turn away without resentment.
