There's no understanding what goes on in peoples' head. I had a similar oddly weird situation at a bus stop with a woman. I would have been fine, thinking she was just crazy, until she made it seem like it was just ME that she didn't want speaking to her. When another person approached and she spoke to them, all I could do was try to ponder how I could have possibly wronged this total stranger. We were all three Black women, so I couldn't even blame it on race. Period behave so odd these days.
