I really enjoyed this story. I liked that we ended off unsure if Sam was crazy or not; we had all the explanations as to why he was insane, but in the end, I think we as readers were more doubtful of his insanity than he was.
One of the things I liked about this was how tight and small the narrative was. It was just a day in this guy's life, but it revealed so much about him and his interactions with the world and people around him. It was a smart piece.
Narrator this week was spectacular, too. He did the female voice well, and switched character voices quite seamlessly. Fun to listen to.
