At a table next to us sat a man with a Prosthetic snazzy looking leg. Max was enthralled.
Later in the week...
Max... "Our skeletons are made out of robots."
Me... "Well not really, our skeletons are bones, covered in muscles and stuff... "
Max.. "No, our skeletons are robots, I saw them."
How do you explain that, we went through the doctor book, max is not convinced. I guess they are kind of robots, controlled by our brains... poor kid thinks he has really snazzy robotic looking bones, just like the mans prosthetic leg.
