from The Golden Compass:

“Why en’t you cold, Serafina Pekkala?”

“We feel cold, but we don’t mind it, because we will not come to

harm. And if we wrapped up against the cold, we wouldn’t feel other

things, like the bright tingle of the stars, or the music of the

Aurora, or best of all the silky feeling of moonlight on our skin.

It’s worth being cold for that.”
