Here’s an exchange between my five year-old son Herschel and his mom while they played a game of Twenty Questions over dinner.
Herschel: Are you blue?
Are you orange?
Are you yellow?
No, and the color is irrelevant.
Are you white?
No, and I just said the color is irrelevant.
What does irrelevant mean?
It means that it doesn’t matter. My color will not help you guess what I am, so don’t waste your questions on this topic. OK?
You get it?
I get it.
Good. So knowing my color will not help you answer the question. That’s why it’s irrelevant. OK, go ahead and ask me something else.
Are you red?
