You reply, I can tell Dave but I can't tell you Barbara. Secrets are
not for sharing.
Barbara is upset by this. Big elephant tears roll down her face and
trunk.
Don't cry you plead with Barbara. If you cry the mouse won't do you
any good.
Barbara stops crying and you then take a thimble from out of your
pocket.
A thimble Dave exclaims. How's that going to help.
You reply that the thimble will catch the mouse which will help poor
Barbara.
What's the secret both Barbara and your other friend ask.
