It's bright, sunny days like this when the mercury dips down to -16°C, and the snow is hard on the sidewalk, when the freezing wind is in my face, freezing my skin, that I'm glad that I never ebayed my parka.
Even so, as I trudged my way against the wind to work, I watched some guy in a beige spring jacket (no hat, no scarf, no gloves) run to the parking lot from a block away, covering his ears with his bare hands. I guess some people would do anything to look as though the weather doesn't affect them.
It's frostbite territory. Bundle the fuck up.
