"Sorry" is just cultural, it's not an actual heartfelt apology. It's not a sign someone has a horrifying lack of self esteem. It already is saying thank you for letting me take up your time. It's saying hey I imposed a little and I realize that.

One of the weirdest things about the past 10 or so years is how literal everyone in the US has become. Every culture has little things little linguistic tics, they are not meant to be taken at 100% literal face value. This is like, why have we lost a connection with our culture, why do we have to be 1000% literal and explicit like it's a nursery school? Things like this meme are utterly bizarre to me.
