All I Wanted Was to Take Care of Business

Just came in the E-mail:

I  was sitting on a toilet at the airport when I heard a voice from the other stall saying:
"Hi, how are you?"

I'm  not the type to start a conversation in the restroom but I don't know what got  into me, so I answered, somewhat embarrassed
"Doin' just  fine!"

And the otherperson says:
"So what are you up  to?"

What kind of question is that? At that point, I'm thinking this is too bizarre so I say:
"Uhhh,  I'm like you, just traveling!"

At  this point I am just trying to get out as fast as I can when I hear another question.
"Can  I come over?"

Ok  this question is just too weird for me but I figured I could just be polite and end the conversation. I tell them,
"No........I'm  a little busy right now!!!"

Then  I hear the person say  nervously...
"Listen, I'll have to call you back. There's an idiot  in the other stall who keeps answering all my questions.

Hoo-Hah
