Intimate Conversation

I was in a public toilet and had just sat down, when I heard a voice from the next stall.
He said, “Hi, how are you?” Embarrassed I said, “I am doing fine.”
The voice said, “So what are you up to?” I said, “Just doing the same as you, sitting here!”
From the next stall came, “Can I come over?” Annoyed, I replied, “Rather busy right now!”
Then the voice said, “Listen, I will have to call you back. There’s an idiot in the next stall here answering all of my questions.”
