Yes, I know that you know that it’s hot outside.
I know that you know this because you are a human being and can feel the hot air hitting your face as you walk outside after work. I know you watch the news where they only talk about the heat. I know you chat with co-workers about the temperature in the office. And I know you have either started or ended at least one email with the phrase “Hope you’re staying cool!” within the past week.
