Opposite Day

I recently, and accidentally, told my boss he was the worst in an IM. In the third person. Almost as if I meant to say it to someone else. I ended up apologizing, but before that I worked on a couple excuses for my terrible faux pas. The best thing I could come up with was, "It's opposite day."

So I must have had opposites on the brain when we were camping in Moab because Jack and I got into a big discussion about opposite while we hung out waiting for the rest of our crew to be finished mountain biking. He wanted me to do something, maybe his shoe? Momma, do it! And I said something like, "well first I have to undo it. Then I can do it." He wanted to know what undo meant and I said it was the opposite of do. What does opposite mean? And so on.

So I just started giving him examples, and it went pretty well.
Me: What do you think the opposite of Up is?
Jack: Down
Me: Left?
Jack: Right.
Me: Day?
Jack:Night.
Me: White?
Jack: Soft. (He didn't get all of them right.)

But the best was when I asked him what the opposite of GOOD was. I was pretty confident he would get it, and I sat back, waiting for him to say bad. But you know what he said, right? He said EVIL.
