Wow, that was great.
Little kids have great horror potential, in part, because they can believably exist in an entirely horrific situation without understanding that it's horrific, if it's all they've ever known. This one hit home espescially. I work with kids, and I've known children who despise one parent for taking them away from the other; they don't understand that Daddy was an abusive asshole, only that he was Daddy, and the only Daddy they ever had. This story felt so familiar, albiet replacing with "abusive asshole" with "demonic monstrous personification of gluttony."
