Time to dust off your inner Lovecraft?

Time to dust off your inner Lovecraft? With knuckle-dusters?

In The Lord of the Rings, The Return of the King, in the chapter Many Partings, we have Gandalf asking Treebeard:

Quote

‘I observe, my good Fangorn,’ said Gandalf, ‘that with great care you say dwelt, was, grew. What about is? Is he dead?’

Ergo, the use of the correct word is vital. In The Wheel of Time, The Eye of the World, in the chapter Web of the Pattern, we find Rand al-Thor in this predicament:

Quote

The dark-eyed girl had a tendency to twist her skirt and giggle whenever she looked at Rand.

Now, what if it had actually read:

Quote

The dark-eyed girl had a tendency to twist her skirt and gibber whenever she looked at Rand.

What kind of a world would that be? What sort of people gibber when you expect them to giggle?

The challenge is to come up with a believable world where that would happen, making a story from the two sentences quoted. Dust off your inner Lovecraft with your best knuckle-dusters, put on your best dancing trousers and get down to the utter king of rock and rool, Criff Lichyard!!!

And show us what you can do!
