I looked it up "Polar Vortex" to see what they are. What I got from it is that they are real bad asses. I'm not interested enough in the science to spend the time understanding it. I don't understand it but I am living it.
I am staying home today, so I have it good, but I just went out to check the mail and the cold clings to your clothes and it was just a brief moment. The mail is canceled for today. The poor delivery people, I'm glad they are staying home.
