On understanding the universe

Juliet has really taken to asking 'why?' and she does it with her own special flair.

For example, an everyday occurrence, like seeing our cat.

J: what is that?

M: our cat. 

J: why is it our cat?

M: because we own him.

J: why do we own him?

M: because we like him.

J: why do we like him?

M: because he is our cat.

J: why is he our cat?

M: ...

Or the ever more perplexing question of 'why is he a cat?'

 Try answering that one to a 3 year old's satisfaction! 

Hint: it's not possible.
