I was reading a little bit of "The Thief of Time" on our car journey back from Sunday lunch, which features the personification of death. Grace asked if death is a skeleton how does he see? Before i could struggle for an answer she has how dead trees see. This is how the conversation went:
G: How do dead trees see?
Me: Well they don't see, trees don't have eyes.
G: What about a person dressed up as a dead tree how do they see?
Me: well they might have holes for there eyes.
G: But trees don't have eyes so they wont have holes so how does someone dressed up as a dead tree without eye holes see?
Me: Maybe they can't.
