I found myself saying internally “..but I was trying to be nice…” and that made me wonder: “am I not nice in the first place?” 😉
It turns out there is nothing as “trying to be nice” there is either you’re nice by your nature and how you act, or you’re not nice. Anything in between can be superficial, acting and not natural, and that does not work for whatever purpose you were “trying to be nice” for.
Bottom line: don’t try to be nice, just be as you are.
