Complete the short story / flash fiction, that has the following first paragraph:
The water sluiced off his body, gathering the blood and dirt that caked his chest and carrying it away in the circling vortex of the drain. There was so much blood and from so many people that he forgot that some of it was his own as well. Dried and fresh, dirty brown and bright crimson, droplets and large patches. His chest was a painting of what he had been through this evening and he was just washing it away. But unlike the blood, his memories could not be easily washed away.
