My 9yo son is trying "No." on for size again. And hanging out with his cousin "You can't make me."
He really doesn't like my flippant replies (he's spoiling for a fight, and I just keep not engaging).
"Duct tape works wonders."
"Really? Why not?" (bambi eyes)
"I'm soooooo ooold and knackered..." (with a feeble voice) "I couldn't even cross the room, you know."
"And yet, I can cancel the internet." (hacker in training, this thought makes him go green and slightly ill looking)
"I think maybe stew for dinner." (completely ignoring his 'no' and changing the subject)
"Okay, what I ACTUALLY meant when I said x, was x... just in case you were confused. But I could mean y. Or z. Z might be interesting. Or maybe instead, x would be preferable?" ((He tried 'calling my "bluff" on this once, and remembered I only offer solutions I'm willing to hand down.))
"Non! Nyet! Basta! Nein!" (etc, in as many languages as I can dig out with increasingly dramatic flourishes)
"I don't think that word means what you think it means." (Inigo Montoya)
His new ace in the hole, however, is "I'm going to go live with dad." Wheeeeeeeeeeeeeee.
