The greatest compliment I ever received from a family member was along these lines: "I don't know anything about WHAT you're doing, but I know you. And I know you'll do the right thing, get whatever training or equipment you need, and make good decisions. So, I'm not any more worried about you cave diving than anything else you do."

FWIW, I think Christine's article was one of the best I've seen for showing to family members because it highlights WHY they died.
