On worms, apples, and chewiness

There are worms, and there are wyrms. One is small, weak-bodied and blind. The other is a wily and fearsome beast, the ultimate opponent. The two words have wildly opposite meanings – or do they?

Note to self: dragons*

"It does not do to leave a live dragon out of your calculations, if you live near him."

 The Hobbit by J.R.R. Tolkien (1937) 

Smaug, by Eric Fraser

* Actually, make that reptiles, generally. Reptiles that slither close and hiss softly but do not blink, and those that skulk quietly in the long grass. And the ones that spit venom. Especially those.  But not tortoises. Tortoises are usually wise rather than cunning.
