Very good points made! I have observed what you speak of - in reagrd to older folks who have accepted the changes, and even have grown to "like" them.
This explains so many funerals where the 70 somthing person who is planning it for a deceased relative requests teh best of the music of Marty Haugen, the St. Louis Jesuits, etc.
They have forgotten the past.......as if it were erased from their memory - having been subtly taught that old = bad, and new = good.
That's because the 70ish year olds were cool 40ish year olds in 1970... that's that 30 - 40 yo age group that forced the divorce rate to skyrocket and embraced birth control... passed the same values down to the kids.
My mother says that many in her generation (she is in her late 70's) fear being thought of as "not with it", or fuddy duddys.
