Probabilites.

“John, you didn’t ride your bike today.”
“No. There’s supposed to be a 70 percent chance of rain this afternoon. I don’t mind riding when it’s cold and I don’t mind riding when it’s wet, but cold and wet is a problem.”

You know where this story is going. It doesn’t have any rain or cold air. More importantly, it doesn’t involve a bike.

So I drove home. Every street was dry. At one point I turned the air conditioning on. It was getting a little stuffy.
