a teenager's explanation

HE: I can't find it anywhere....

ME: I think I hung it up, out in the barn, next to where the basketballs are kept.

HE: Well, I couldn't find it. I looked everywhere.

A while later he went out to the barn and looked again. Still later, the conversation continued after I came inside from going out to the barn, where I found it hung up, next to where the basketballs are kept.

ME: Here you go. It was right where I said it was.

HE: Thanks. I guess I looked everywhere but there.

ME: . . . .

This was said without a hint that he understood the implications of his comment. In his mind, it was just a reasonable explanation.
