But...your Dad is 72!

So, here's a brief view into my left hand. I'm putting it here so I can let it go.
It's obvious now that something is 'wrong' with me because I can't go anywhere without Sparkle Ruby. So, people feel it's appropriate to ask me .."ooo, what happened to you?" I realize they ask in this way b/c they don't expect a sad answer like-I have a disease and a fake hip and it's rattling around in my pelvis so I have to have major surgery- they probably think I'll say I hurt my foot, or broke my toe or fell on my tail bone. But, the minute I tell them the truth most people- and do mean most- instead of saying "that sucks, I'm so sorry" feel compelled to tell me about their father or grandfather or great-aunt (basically people who's average age is usually in the low to mid-70s) who had a hip replacement. As if this is not enough, many people then either rattle off any and all information they may have gathered about this procedure, the expected life-time of the parts, the pain associated with recovery OR better still, the ways in which their loved one screwed up the hip by getting out of bed too soon, or taking a spill and popping it out of joint (I had someone tell me in great detail how "it popped out and popped out and was never the same since).
Annoying right? And, I really do try to be gracious and recognize they are trying to relate to something they can't possibly understand, and also they probably do feel badly, and I know it doesn't compute, an otherwise healthy woman struck down and appearing crippled in front of them. But honestly, it's okay to shut your mouth and just say, "gosh I'm sorry, that must be hard".
