“mum, why is there a trolley there?”
“Because we’re at the supermarket, honey.”
“That trolley is broken.”
“How do you know?”
“The wheels have fallen off!
The wheels have fallen off because somebody didn’t be careful with it.
They needed to be careful with it and they didn’t. Now it’s broken.
If I had it I would be careful with it.”
Mmm. Great logic. Apart from the part about the trolley being a picture on a sign!
That is one smart kid you have there. Good luck with that.
