restroom etiquette

Let's say you run into an acquaintance on the way to or in the restroom (or as i like to say "washroom") at work or school...you start chatting and then both head into your respective stalls...does the conversation just come to an end? do you finish that last thought as you tinkle? what if you finish first, do you say "bye, see ya later!" as your potty-partner is finishing their business? these are my deep thoughts for the day.

gotta love how restrooms are the stage for so many potentially awkward situations!
