Do you promise not to tell?

I wouldn’t tell a soul!
I’ll be silent as a storm.

You won’t tell a soul?
My lips are sealed!
’Til I open my mouth again.

Can you hold your tongue?

Don’t worry, mum’s the word!
If I don’t run into anyone.

And you won’t breathe a word?

It’s wholly between me and you!

And a few other people

You’ll keep this just between us?

I’ll save it under my hat!
But hats get itchy after a while.

Do you promise not to tell?
I won’t let the cat out of the bag!

Unless it asks nicely.

Can you keep a secret?
I don’t think you can.?
