Kids are stupid
Well, mine is.

Making coffee one morning, for the wife, I looked over and saw my then 5-year-old son reaching slowly towards the near-boiling kettle.
"Son," I said, "don't touch that, it's hot. You'll burn yourself."
He looked up at me.
"All right, dad."
I turned away to get a spoon from a drawer, then turning back noticed a little hand once more reaching out towards the kettle, which by this point was puking steam all over.
"Look, son, you really mustn't touch it. It's boiling hot, it'll really hurt."
Again he looked me in the eye and said solemnly,
"OK dad."
I turned away again to get the coffee from the cupboard.
"AAAAAARRRRGGGGHHHH! I burned myself!"
Terrible father that I am, my first response was not sympathy, or even concern, but rather "Oh, for the love of...", swiftly followed by "Oh well, maybe that way he'll learn."

He didn't.

You've just described my youngest
"Don't touch that, it's hot!"
"How hot?" (touch) "WWAAAAA!!!!"
My kids are Muppets.

A mate of mine does this in restaurants.
*Every* fucking time the waiter says "Mind the plate sir, it's very hot", he just has to check. Then wonders why I'm laughing at him holding his singed fingers.
