When my son was not yet 3yo, we were at a Macca's sitting outside near the playground.
He'd found a friend, a young girl that he had been playing with for 5 or so minutes.
Now, as a lonely child, he was quite possessive when it came to making a new friend.
The young girl began to walk away from the playground, possibly because the food was ready, and she'd been called by her parents.
The next thing I hear from bltn jnr is....
" where do you think your going ? "
It's become one of my favourite lines to use with him, even though he doesn't remember it.
