?? Saying "hi" is about the most basic and almost meaningless human interaction a person can indulge in.

I would think that saying "hi" WOULD even work if you walked into the wrong restroom. I know, because I have actually witnessed EVERY situation described above and more, yes including people in the wrong restroom, and funerals, and so on.



I have found that unless someone is already pleased with your visual and auditory presentation, that there is NOWHERE that is a "good place and time" to try to initiate a meaningful interaction with them.
