My friend lost his legs while we were playing on the train tracks one day not that many years ago. As such, he's missing most of his legs below the genital area, so he's missing a little more than above the half way point of his leg. Now, I like to joke around with him because of it, cause I was there and cause I pulled him away, but because we're really good friends.
But his family doesnt get it, so one day his family was telling the story of what happened to company, and I said what I always do when I joke around of him. I said "well, at least the wheels make it easier to catch a train, hunh?"
yeah... I saw the words floating in front of me, just slipping through my grasp as I realized what I said. In retrospect, my friend and I find it funny still, and he still laughs when I say it. But his family always gets on my case, asking me my opinions on his wheels.
