Chris,
I couldnt help but feel awful about what happened to your co-worker. We can all learn that lesson of keeping our spirits up when things get tough. It's also good to know that he has friends like you around to help him through. I commend you on that as well. Here I sit, looking at my right pointer finger which was almost lost due to a forklift of all things. Just knowing that they were discussing the possibility of amputation pretty much brought me down to nothing. Just as sombody else mentioned. This was nothing compared to what your friend went through. I'm glad that was all he lost.
