"Can daddy have the ball?"

The boy hands over the ball.

"Thank you!" I say.

(later)

"Can daddy have the remote control?"

He hands over the remote control. "Dee deeee," he says, with the exact inflection I used to say "thank you."

"That's right, I should say thank you. Thank you."

I spend a lot of time asking him to give me stuff. And now, every time he gives me something, he says his version of thank you. Oh, so cute, you say. Maybe so, but cute or not, it's wrong.

"No son, when you give me something, I say 'thank you'. You say thank you when I give you something. Got it?" I handed him a toy. Nothing.

He handed it back. "Dee deeee."

"You need to work on your listening skills."
