One of the problems with moving forward is that there are times that require looking back--and not with nostalgia.
I was recently visiting with a friend who is a Vietnam veteran, describing "then" and "now."
He
described it like this: "When I came home, I sort of put all that
stuff in a package. You know, when I was in country, we always said
"When I get back to the world, I'm gonna...etc. etc." It was sort of
like Vietnam was "another world."
