Hello, I'm William.
And I'm Graciela.
Will, I hope you've brought that poor cat for a very good reason.
It's terrified.
Well, I wanted to explain an English phrase, Graciella and I brought Whiskers in to help.
Well, he's not very happy about being stuffed into that bag.
You'd better hurry up and explain your phrase.
Ok, ok.
So, right.
I'm gonna tell you a very big secret.
Oh.
But you must promise never to let the cat out of the bag.
No, we must let him out.
He's unhappy, Will.
No, no, I mean in English.
When we say you mustn't let the cat out of the bag,
it means that something is a secret and that you mustn't tell anyone.
Ah, so it doesn't literally mean there is a cat in a bag, it just means that there is a secret that must be kept.
