I thought most people by now had at least read or heard of Kubler-Ross' work or the general wisdom that has come from it, and had "gotten the message" about this; so sorry to know that your well-meaning friend hasn't. (not meant judgementally, H-Grrl, I'm glad you've found it and read it as well.)
Not taken that way at all, dellaroux. I skimmed the book many years ago but must have lent out my copy and never saw it again. Recently I ordered it for someone I know who is terminally ill (who had heard of the five stages but didn't know anything more about her or her work), so I decided to get myself a copy at the same time and "really" read it. Most enlightening.
