This morning as a fixed Elisabeth's hair we had the following conversation:
E: "How do they make glass?"
Me: "They melt sand and while it is really hot they poor it out into glass."
E: "Is that how they make plastic?"
Me: "No, I don't think so."
E: "How do they make plastic?"
Me: "I'm not really sure."
E: "Paw paw will know."
Me: "Why do you think Pawpaw will know?"
E: "He's just kind of like that. I don't know he's just my grandpaw."
It made me laugh. Elisabeth truely believes the notion that if they're older they're wiser.
