Everyone dismisses it because he's in a mental hospital, but is he being delusional? I deliberately don't say one way or the other. I like ambiguity. 🙂

I love open-ended stories like that! Since my mother passed, my sister and I have been reading a short story every week with my father, and I'm struck at how much he really loathes ambiguous endings. If the story doesn't end with the bad guys punished and the good guys triumphant, he gets very frustrated. But I really like a story that ends with a feeling that there might just be things you'll never know!
