Deaf old idiot

"Where are they," I asked, tapping my feet. I had been waiting for over an hour. I phoned home, and left a message. "What's going on?" I plaintively asked.

We had agreed to meet at the mall. We're having an unprecedented heat wave in Ottawa, and we thought that dinner out was infinitely more appealing than sweltering at home with the stove on.

But where were they? My wife said six, and I had been at the mall since quarter to. Why weren't they here?

Well, my wife showed up on time, just as I had. But she showed up at the right mall.

I am a doddering old senile idiot. 8=)
