There was a time *when they'd still fall for it* when DH used to tell the boys that olives were black grapes.
It's wrong but I can't help giggle when the little one realizes I've said "no" to something he wanted. Usually it goes like this:
Piratebabe: Want wat' Tummas? (Thomas)
Me: No, not now, sweetie.
He starts to walk towards the movie cabinet with a grin, then he stops and his little face crumples when he realizes I said yes and he either starts to pout or cry. It's wrong to laugh at it but it's just funny how it's kind of a double take reaction.
Also funny, he went up to our cat Sherlock and petted him saying "Aww, Shewwy, nice kitty!" He was very gentle with him, but the cat gave me this look as though he was thinking "I deserve to be canonized for putting up with him..."
