I was in the public toilets & had just sat down, a voice from the next cubicle said, "Hi, how are you?" Embarrassed, I said, "I'm doing fine." The voice said, "So what are you up to?" I said, "Just doing the same as you, sitting here !" From next door, "Can I come over?" Annoyed, I said, " Rather busy right now." The voice said, "Listen, I will have to call you back; there's an idiot next door answering all my questions."
