Before we talk about the cold weather, we need to figure out the specifics of our relationship. Let me explain.
When talking on the phone to people who do not live here: "Oh, I wouldn't say it's cold. Sixty-seven below, you'll get that now and then. Builds character! Tonight with the windchill, all molecular activity is expected to cease, so we might bring the plants in. Walked all the way around six lakes this morning. You just have to remember to wear lots of layers and periodically set your pants on fire."
When talking with guy friends: "I took out the trash in my underwear." "Oh, you put on underwear? Weak!"
When talking with a spouse: "Why do we live in a place where the air wants to kill you instead of moving to Arizona where you can walk to the car without losing a toe?"
When talking with a casual acquaintance: "Nippy out there! Tad brisk! I thought we'd dodged it this year, usually get it in January, but heck, gotta have that deep-freeze week, right? Ha ha! Something to remember when we're complaining about the humidity, right? Well, nice chatting, see you later for more meaningless mindless mouth-moving that reveals nothing of our inner struggles."
When talking to the dog: "It's OK. If I were you, I'd go on the rug, too."
It was dismaying to look at the weather forecast and see nothing but single digits. It was inevitable that the deep cold was called "bitter," just as all milestones these days are "grim." (In fact, Merriam-Webster will probably call the word "grimilestone" in the next dictionary.)
But why bitter? That's a flavor. Also an emotion.
