I walked into a public restroom today. There was a guy in a stall... pants around ankles... talking loudly on the phone. About the time I stepped to the urinal, he got off the phone. I finished my business. Walked to the sink. Was washing my hands when... ...this guy opens his stall door... and walked right out. I wanted to say, "Hey man... wash your hands!" But I didn't. Should I have? Do we as a developed civilization any duty or responsibility to address these people in any way at all?
