I can't believe this happened

I was on the toilet, and shortly after I sat down I heard from the stall next door, "Hi, how are you?". Embarrassed but not wanting to be rude I said "doing fine?" Then I hear them ask "So what are you up to?". ?!?! "Um..." I said "Same as you I'd guess. Just sitting here." Then I'm completely caught off guard when asked "Can I come over?" "I'm kind of busy at the moment" Annoyed I responded. Then I hear "Listen, I'll call you back later, the idiot in the next stall is answering all of my questions."
