I don’t ”look” married, whatever that’s supposed to mean.

I’m sick of guys harassing me when I want to be left alone and a lot of other women are too. I can’t even go for a walk without being catcalled or beeped at, and I’m not even attractive. JFC.
At any rate, your “method” almost never works, and it would be very easy for someone without
excellent social skills to come off as
creepy, especially individuals who had problems with that in the past.
People need to ditch the cold approach, pursue personal growth, and look for more natural opportunities to get to know people as friends.
I think if its done in a friendly way and so long as the man can pick up the early cues they are infringing on personal space/privacy. Yes of course, I wouldn't want men trying to chat up my daughter. Fortunately she is the obstinate type.
