Jbennett,
I too had many such experiences from the same kind of attitudes that you are describing. A few such comments still p me off to this day. One co-worker of mine ridiculed me when I told him I would be off work for about two months. He claimed that my surgeon was BS-ing me and no way would I return sooner than four or six months. (You know the story, his 80 year old Aunt Maude had hip surgery 25 years ago and she was never right after that.) You should have seen the look on his face when I walked in to my workplace at six weeks to visit. No cane or crutches and only a slight limp. Oh well, don't let the idiots get you down. You picked one of the best surgeons in the world and your results will be amazing.
Oh yeah, your comment about the wife being on board. Mine was very much against me going all the way to S.C. for hip surgery. It took me a while to convince her that it was the right decision. And after going along with me for my surgeries and seeing how much better our lives are with my hips fixed, she is just as enthusiastic about HR and Dr. Gross as I am. Your wife will be the same way, I'm sure.
