Wow, glad you're ok...
The only situation I have to compare with that (and it isn't the same thing) is when I was out at the shooting range, I went out to swap out targets, I told the guy next to me that I was going (just the two of us out there), he said ok (or I thought he did anyway).
I walked out to the target and had a bullet pass by me, he had fired off another round.  Since he was using his scope, I guess he didn't see me.  It wasn't "right by" by head, but dammit it, that doesn't matter.  I was out in the line of fire.  I dropped to the ground, afraid I was going to get shot, then I screamed at him to stop shooting.
He was really sorry, appoligized over and over.  I know he didn't mean it, but I went home, that was enough shooting for me that day.
