I was in the public toilets and 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".
