Talkative Public Bathroom

Leaving Minnesota for Colorado, I decide to make a stop at one of those rest areas on the side of the road. I go in the washroom. The first stall was taken so I went in the second stall. I just sat down when I hear a voice from the next stall... 

- "Hi there, how is it going?" 

Okay, I am not the type to strike conversations with strangers in washrooms on the side of the road. I didn't know what to say so finally I say: 

- "Not bad..." 

Then the voice says: 

- "So, what are you doing?" 

I am starting to find that a bit weird, but I say: 

- "Well, I'm going back to Colorado..." 

Then I hear the person say all flustered: 

- "Look I'll call you back, every time I ask you a question this idiot in the next stall keeps answering me."
