I don't know if it's because he's intelligent or because he's my kid...

But somehow Nathan (age 5) has discovered sarcasm.

We had this conversation this morning.

Me: *held out a banana* Nathan, do you want this?
Nathan: Yes
Me: *hand it to him*
Nathan: What? Am I supposed to snuggle it or something?
Me: *puzzled look* No..eat it.
Nathan: Well, I can't open it.

That's when I realized he was being sarcastic. Little stinker.
