Of Real Worlds As Bright As Thine

We've had some frightfully clear and cold days lately. It always strikes me as counter-intuitive that overcast days with snow can be significantly more warm than clear, bright winter days with a brisk wind. It's as if the outside is deceptively brilliant and inviting, but like a will-o'-the-wisp from a fairy tale, it's an illusion of false warmth and security. I am of course that foolish wanderer of yore who can't resist following the flickering lights...if I chase the sun long enough spring will arrive, no?
