"a" and "b" do not always equal "c"

It's hot in here.

So get up and turn the a/c on.

No.

Why?

Because if I'm not working out, I'm a big fan of sitting on my ass in front of my computer.

But you're sweating and grumpy, which means more typos, which means you're angry and pounding on the keys. Which expends more energy and makes you sweat more. You've been sweating all morning in 200 percent humidity for your workouts. You've got modern technology just ten feet away.

My right foot is twitching for some unexplained reason. It's annoying.
Also, I've got a necklace of bug bites because I seem to be tastier when I sweat humidity.

What does that have to do with the a/c?

I'm burping tacos.

Get up and turn on the a/c.

Ok.
