Everybody's hobbies are much more interesting to themselves than to anyone else, whether that be climbing or crochet. Let's not get too elitist here.
As for parents, I have to say that mine are great. They're east coast city slickers and don't understand or approve at all of what I do, but they respect that it's something I love, and even buy me the gifts I want rather than what they want me to have. I got an ice axe for Christmas last year, and a Schoeller jacket this year.
