Besides meeting my wife this way, there was one girl who rather coldly rejected me that I later ran into via another social circle. I apologized if I had made her uncomfortable and she told me that even though she wasn’t interested she was also somewhat flattered and that the incident made her day.
I think with sexual harassment in the world and all these apps everyone overthinks things and think just walking up to a stranger is for boomers or pick up artists. Really it’s just the normal human interaction that worked for a couple million years and still works today. And at least for typical heterosexual dynamics, the ability to make eye contact and say “Hi, my name is” will always be more impactful than a Bluetooth signal.
