Lying in bed with my wife, just starting to doze off, when the doorbell rang. My wife nudged me, as if I hadn't heard the bell, "Go and see who it is." she said. I looked at the clock, 2:15am. I opened the door and a guy was standing there, holding his coat across his chest to keep the wind out. He said, "Is there any chance you could give me a push?" I could feel the biting cold through my dressing gown and answered him with as much sympathy as I could muster, "I'm sorry, it is much too cold for me to risk getting hypothermia." The guy turned away and I closed the door. When I got back to bed my wife asked, "What was that about?" I explained. She said, "Come on dear, what if that had been you and had needed a push?" "AND look at the time, who else could help him?" "Sure five minutes will do it." "There's a dear, pull on some clothes and go and give the guy a push." Doing as I was bid, I ventured out into the dark, freezing night. I couldn't see the guy anywhere. Maybe he had gone. I'd better not go back to bed without at least trying to find him. So, I called out into the darkness, "Hello are you there?" A voice came back, "Yes, I'm still here." I couldn't place the direction of the voice, so, I asked, "Where are you?" The voice came back, "I'm over here on the swing."
