The grandboy’s taken the ‘why” question out into psychology realm now.

Grandboy: “GWUMPA gwumpa i’m thirsty gwumpa I’m thirsty.  May I have some water please?”

Me: “Ok sure [I hold two cups out] which one would you like, the red cup or the blue cup?”

Grandboy: “The RED one gwumpa, red one please.”

Me [filling up the red cup]: “Ok here’s water in the red cup.”

Grandboy: “Why?”

Me [confused]: “Why what?  Why am I pouring water or why did you pick the red cup or why did you want water?”

Grandboy: “Why i can choose the RED cup, gwumpa?  Why red?”

Me: “O I don’t know.  You chose it.  Why did you choose the red one?”

Grandboy: “I’ll have to think about that.”
