Restroom Stall

Traveling down the interstate and needing to use the restroom, 
I stopped at a rest area and headed to the restroom.

"Hi, how are you?" I'm not the type to start a conversation in the restroom and I don't know what got into me, But I answered, somewhat embarrassed, "Doin' just fine!" And the other person 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 Cell phones, don't you just love 'em ! May you always have love to share, health to spare and friends that care!
