A very small animal and a very large one, and a lesson about kindness. And about asking politely, which, when the other person is a lion, is extremely important.

Aesop’s Fables · Part 1 · Modal verbs: permission, requests and offers
Can, could, may, would you, would you mind, shall I and can I: the grammar of asking, allowing and offering, begged by a mouse, granted by a lion, and precisely footnoted by Philo.

A very small animal and a very large one, and a lesson about kindness. And about asking politely, which, when the other person is a lion, is extremely important.

This is my favourite. The small one wins.
After Aesop
A Lion was sleeping in the sun when a little Mouse ran over his nose. The Lion woke with a roar and caught the Mouse under his great paw.
“Please, King of the Beasts,” squeaked the Mouse, “may I say something? Could you let me go? I’m so small that I wouldn’t even fill your mouth. And perhaps one day I could help you.”
The Lion laughed so much at the idea of a mouse helping a lion that he lifted his paw and let her go.
Some days later, the Lion was caught in a hunter’s net. The more he struggled, the tighter the ropes held him, and he roared with anger and fear.
The little Mouse heard him and came running. “Shall I help you?” she said. And she gnawed through the ropes, one by one, until the Lion was free.
No act of kindness, however small, is ever wasted.
Can, could, may: asking for permission

The Mouse says “may I say something?” to a lion who is about to eat her. Isn’t that a bit too polite?

Not when it’s a lion. To ask permission, we use can (friendly, informal), could (more polite) and may (the most formal and polite). Can I sit here? Could I borrow your pen? May I say something, Your Majesty?
Giving and refusing permission

A footnote. When we answer, we don’t use could. We say: Yes, you can, or Yes, you may. And to refuse: No, you can’t, or, very formally, you may not.

Quite right. Could in a question is only there to be polite. Could I go? Yes, of course you can.
Could you, would you, would you mind: requests

Then she asks: “Could you let me go?” That’s asking the Lion to do something, not asking for permission.

Exactly. For requests: Can you…? Could you…? Would you…? and the most polite of all, Would you mind + -ing: Would you mind lifting your paw? Careful: the answer “No” means yes, I don’t mind.
Shall I, can I: offers

Shall I bring you a lamp, Sophia? Can I carry those scrolls?

Thank you. The Clerk is making offers: Shall I…? and Can I…? (or I’ll…). The Mouse makes one too, when the Lion is in the net: Shall I help you? That was the best offer of her life.
The moral

The Lion could have eaten her. Instead, he let her go because she asked well, and he laughed. And the laugh saved his life.
