I was in a public restroom. I had barely sat down when I heard a voice in the other stall say: "Hi, how are you?"

Me (embarrassed), "Doin' fine, thanks." 

Stall: "So what are you up to?" 

Me: "Uh, like you, just sitting here." 

Stall: "Can I come over?" 

Me: (now with an attitude) "No, I'm a little busy right now!!" 

Stall: "Listen, I'll have to call you back. There's an idiot in the other stall who keeps answering all my questions!"
