They have it.

Last night I was off to a barbeque with some friends of mine and their small people, Three and Seven.

I was sitting in the back beside Seven, who was in the middle. She stretched her (very long for being only seven) legs out, put them on the arm rest in the middle of the front seats and lazily said to her father, 'Could you move your arm, cowboy?'

I didn't realise seven year olds could be so impossibly cool.
