They guy was hysterical. It was directly on top of his head and he couldn't see it, so couldn't assess how bad it was. All he knew is that it hurt like a MF and blood was streaming down his face. I tried to assure him it was superficial, but he was pretty shaken up. We got the bleeding mostly stopped by the time the EMT's showed up.
I've been cut there a couple times. Bled like my head had its period. It's easy to understand someone freaking out if it's never happened before. Glad you were there to help him out.
