I want to know that, too... that's the problem with just following the Muse.

I know that (in my mind) I'd been mulling over Tralow and his explanation for the reasons why corporal chastisement (or discipline) was so popular in Christian nunneries. A rough translation (off the top off my head) would go like: ... of course, she suffered from the lung evil and was almost constantly aroused. And then, beatings pushed the blood towards the centre of the body to give her some relief.
Or something to that effect.

How that mixed in my mind with a delicate glass sculpture spinning on a chain and Changmin stretched out on a marble floor.... only the muse can tell.
