Filthy the Snowman

It was seriously dirty snow, even by New York standards. But they didn't care. They were 11 years old. In an hour homework would start, dinner, all that. So why not at least try, even if there were five cigarette butts in the torso alone. When I asked them for a picture one of them pulled a tiny, wilted carrot out of his pocket and held it proudly near the "head" while all three mugged.
