Today at dialysis, I was about to walk into the clinic, and a young surgeon was sitting right outside the door in the vending area. He asked me if I was on dialysis, then proceeded to say that I was so young to be on dialysis! No, I just routinely walk into the hospital's dialysis unit with a big, fuzzy blanket for shits and giggles. Two bonehead statements in 10 seconds! And this was a surgeon!! I should have said he looked too young to be a surgeon.
I met this guy recently. I was telling him all about my situation - dialysis, etc. He says he knows why my kidneys failed. I said that I know why - diabetes and hypertension. He said (with an air of authority) "No, that is not the reason. You did not drink enough water!"
My trouble is that I think of the smart ass comebacks well after the moment has passed.
