2. “You look great, did you do something different?”
This right here has to be the most insulting of things to say. While the ones mentioned earlier made things awkward, this one feels like a slap on your face. You are literally saying, that doing something different to my face has made me look better. In other words, all the time you have seen me before, I have looked like a homeless person or worse. The chances are that every time you say this, the person will walk away and probably never speak to you again. I mean, I get it that you want to compliment the person but why add the “have you done anything different” bit? Simply stating “you look good” is fine.
