Out of the mouths of babes!

A delightful conversation overheard in the bookstore today, that caused mirth all round.  A father and two young children were browsing the shelves and chatting about their finds:
"Oh look Daddy! Buzzy Bee!" Younger child had spotted this book:

Flying Kiwis: A History of the OE 

"And look at this one dad!" Older child held up this book: 

Grumpy Old men

"Oh, so I suppose that's me is it?" asked dad.  "Not sure", said  older child. "At least ... you're not old!"
