Ari, Ari, quite contrary

It seems the Terrible Twos have descended upon us at last. It was inevitable, I guess, that the odd tantrum and naughty bit of behaviour should creep into our lives, but I've been trying to deal with it for the best part of two weeks now and it's quite a change.
Let me start by saying that our Junior Chop has not suddenly become some crazed terror of a child. Far from it. But he's starting to test us in little ways, that sometimes results in feet stamping, tantrums and the occasional wailing crying mess.

Another change has been a strange contrary turn of phrase, eg:
Ari: What's that?
Me: That's a crane.
Ari: That's not a crane, that's a truck!
Me: Oh, a truck is it?
Ari: No, not a truck! A crane!

And so on.

I have no idea what's going through his little noggin' when he has these strange conversations, but I'm sure it's all normal and part of figuring out the world. Or maybe he's just devised a superb way of frustrating his parents.
