EMBARRASSMENT

I was barely sitting down 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 men's restroom
but I don't know what got into me, so I answered, somewhat embarrassed, "Doin' just fine!"
And the other guy 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 him, "No........I'm a little busy right now!!!"
Then I hear the guy say nervously...
"Listen, I'll have to call you back. There's an idiot in the other stall who keeps answering all my questions!!!"
