2yrs ago I literally just said "you look nice, and it's cold out so good for you putting in the effort" as I was walking the opposite direction as a strange woman. DO NOT DO THAT, recognize for yourself that they are there, but do not acknowledge people. She threw a hissy fit and tried to make it look like I was harassing her, her fat but much nicer friend whom I also complimented took it well and said "it is cold", the pretty bitch literally started walking like a dinosaur and had a meltdown because I just left. You don't need these people. Just act like they are an annoyance to even be in your presence and get a dog or two. It's better that way, permanently.
