Wednesday 23rd January 2013: 2.38pm. Speaking of brrr, something that I never realised about snow at minus 15C or so is how like sandpaper it is. When you're walking to work and it's windy, your face actually gets exfoliated. Which is painful at the time. I'm told if it gets even colder, it actually gets better because the snow no longer melts when it hits your skin, so it bounces off instead of freezing your face off. Which would be nice.
