Might as we'll be turned to stone too for all the good I'd be on my own....

WWYDI a robin "psst"ed at you?

Follow it.

WWYDI you met a talking beaver in our world?

After getting over my initial shock, I'd go back to its dam with it.

WWYDI stumbled across a boat in our world that looked very much like a Narnian boat?

Wish it was mine. And take pictures.

WWYDI you found out that CS Lewis was actually still alive?

Well, get in contact with him, of course!

WWYDI Aslan appeared to you in a dream?

He did once. (I had a dream in which all that happened was that I somehow entered Narnia and met all the good characters.) and though I don't remember details (boo), I do remember it happening.

WWYDI a mole offered to plant and take care of your garden?

Be thrilled and say "Yesyesyesyesyes!"

WWYDI you met Eustace in England before he was dragoned?

Smack him on the head and tell him to be good and to listen to and respect cousins!
WWYDI Someone ruined all of your copies of The chronicles of Narnia(including movies and audio books if you have them)

Mourn their loss. Particularly of the books.

WWYDI you were offered a year of education in Calormen?

Laugh, but take it anyway just for the sword fighting and horseback riding that I'm sure they'd offer.

WWYDI you were offered singing lessons by a mermaid/merman?

Take it on a in-my-free-time basis unless I end up being too shy or embarrassed to do so.

WWYDI you forgot that you'd invited a Centaur to stay for the weekend?

Be really embarrassed. Then go grocery shopping.

WWYDI you were invited to spend a week at Professor Kirke's house?

Jump on it!

WWYDI the Macready caught you touching historical artifacts?

Run and hide in the wardrobe!
WWYDI a giant charged you?

Hope that his running aim is as terrible as his throwing aim. Either way, I'd be booking it as fast as possible!

WWYDI you went treasure-hunting with dwarves and made a jackpot find?
