When my son was about 4 years old, I said, "Danny, I'm bored."
He looked at me quizzically and said, "you don't have to be bored Mum, you can just sit in the gutter and crumble up a leaf." From the mouths of babes.
His wisdom has always remained with me.
* We didn't live in the gutter by the way. Just kid stuff, where you build dams, and sail matchbox boats down.
