A long time ago, before the days of cell phones, I needed to call home, and the only pay phone I could find was in use. So I stood to the side and politely waited until it was free, thinking it would only be a couple of minutes.
Five minutes went by, and still the man was on the phone. He was just standing there, not saying a word.
Two more minutes went by, and he still wasn't talking.
Finally, I tapped him on the shoulder and asked if I could use the phone. I really wouldn't be long, but needed to make an important call.
"Hold your horses," he responded, covering the receiver.
"I'm talking to my wife."
