So I know kids are getting older earlier, but isn't 4 a bit young for a teenager? This is Sam's conversation with his mother today:
"What did you do at preschool today?"
"I don't know."
"You don't know?"
"I don't remember. I don't remember anything."
"Did you do French?"
"Nope."
"Did you do Music?"
"Nope."
"Did you do Art?"
"Nope."
"Did you do Science?"
"...yes."
"Ah! What did you do in Science?"
"I don't know."
*pause for comedic fourth-wall-breaking look*

As it turns out, his day - apparently - consisted of going outside once, putting blue cylinders in order, and then sitting on the floor.

Money well spent, I'm sure. :)
