I told a guy today “you look so fashionable!” because he did, good looking guy literally young enough to be my kid, in a great outfit that looked intentional, and got back a “thank you!” Because he knew I was not chatting him up, just legitimately complimenting him. I could always do this with women, but not men.
Just happy, I am happy about it.
I could be wrong, but I don’t think this is an “other men” situation.
Either way, build each other up!
