During the summer holidays we save boxes up for some twins who then make things out of them.
One made a castle the other made a space ship. On showing me the picture of the ship he described all the bits , the thruster , the fins etc.
I asked him if he was going to the moon in it , he looked at me as if I was dirt and then replied ” no ,it’s a cardboard box”
A 4 year old well and truly put me in my place.
