longish response
@Angle I think it's more that everyone tends to see through their own eyes. Sorta like how everyone sees themselves as the bullied victims in high school, even the bullies.
WORSE when you see someone growing up as a kid, you might have problems seeing them as anything but. So the Boomers don't just have "well we saw Xers and Millenials as fairly dependent kids, what do you mean treat them like adults" but they've ALSO internalized the infantilizing way the Greatest Generation looked at them, in part because the Greatest Generation's whole schtick was busting ass for their kids and therefore not being around all that much.
It's a mess. Anyway, thanks for your patience with this stuff.
