When I was a little kid, the Vietnam war was *forever* ago, the withdrawal having happened when local third graders were born. Meeting Vietnam vets still on active duty (my stepdad was a reservist) shifted *forever* ago to "before my parents were born". Now it's more like "well before WWII".
Like, I anticipated that stuff I actually remember happening wouldn't feel as far away the older I got, because grown-ups said that *constantly*, but I didn't expect that "a long time" would end up fixed to roughly double whatever my current age is.
