A friend, who I haven't spoken to in a while, was "walking his dog" through a graveyard two weeks ago, and a gravestone fell on his foot and took his big toe off! Like, I mean clean off. Got rushed to the hospital, where they re-attached his toe to the foot, and for a week or so they were waiting round to see if it would take to his body again. At one point things looked fine if a little distorted, with the blood flowing through. But two days ago, a day before he was due home, the toe died, and they had to permanently remove it. What makes this worse is that he's a very, very promising long-distance runner; of all the things to lose, and he loses something integral to his would-be career. Needless to say, he's devastated. I feel so very bad for him, it's unbelievable. I don't know if I believe that he was (just) walking his dog when it happened, but even so, what a freak accident, a tragic one no less.
(You should have seen the pictures. They were pretty bad, as you can expect.)
