Your face was bright, as you looked at the blood splayed across the floor, with the kind of joy I now always associate with small children, who can find wonder in things they do not understand.
I once walked in on my nieghbour in her kitchen, with a bad head wound (we established later that she'd fainted and hit it hard on the sink). Her one-and-a-half years old child was playing in the blood.
I think it's the most disturbing thing I've ever seen.
