I was reading a while ago on Reddit about a guy that was assigned as staff for his friend's wedding, so he had to welcome all guesses. After the party, an old lady came to the guy and said "she is only 14". Apparently, he welcomed a female guess that was 14 and they interpreted it as him hitting on her. Observe that it is almost always women who see it this way.

Almost all guys have stories like these, especially average and ugly guys because they are seen as threats by just existing. I remember a girl that was very nervous as I started a conversation with her in a Wendys. So I stopped talking to her to avoid further discomfort. However, it was just a normal conversation about how slow that Wendys was. If I was more autistic, I probably would have continued the conversation and she would feel "traumatized" so I'm empathic to a lot of guys that don't interpret social cues very well. I also have received the look of "how dare you ask me out" after asking a fat woman to just move out of my way through a narrow hall or overcrowded place.

Not only that, but often you observe this behavior from women when you just smile them, or say them hello, etc. It happened twice to me that two female workers in different occasions called me out for calling them "mom"... I realized that the reason was that I said "one mom" for a short of "one moment". Of course, they did not see that as harassment or anything, as supposedly I'm not weird guy in any other way, but the did not see it as professional.

It gets even weirder. Sometimes it is the woman that starts the interaction with a common question or comment, and if the guy continues the interaction they interpret it as the guy trying to hit on them.

I'm sure a lot of women claiming "men ask me out a lot when they get out of the house" are talking about these experiences and interpretations of them, rather than genuine attempts from men to pursue them. In fact, I would say that it is up to 90% of supposed approaches from men. I rarely see a man approach an unknown woman, they rather focus on close women they know instead, but I hear a lot of guys telling me experiences as these.

I don't think guys shall be concerned. It is very unlikely women will escalate that into a full conflict. So I suggest guys to not take it that seriously. However, it is very disheartening for guys and an imaginary ego boost for many women.

TLDR: Most men "approaching" women are just misunderstanding from women about normal and common everyday interactions.
