My 9 year old son was sitting on the toilet, when this conversation took place:
Z: "Mom? Did you know if you're a person who's blind, you can still eat?"
Z: "Yes! If you're a person who is blind, you can still find your mouth, even if you can't see it. You can find your mouth so you can eat!"
Me: "Wow, that's awesome. Good to know."
Z: "I mean, like, you won't ever go hungry. You can find your mouth if you're blind, even if you try to miss it!"
Me: "click click, clickety-click....."
Z: "Stop it!!!! Don't you DARE put this on facebook!"
