Here's something my wife and I discussed a bit last night.
She will occasionally now, partially to tease me but mostly as a compliment, say "aren't you the sweetest?" — after some sort of interaction I have with a stranger.
And the fact is, when I was a guy, I was always considered to be SUCH a "nice guy." And it's true, I was. But I also always found myself holding back, dialing it down. Things I'd want to do or say, I knew were too much, so I wouldn't.
And what is glorious now is, that filter is removed.
Some of it is the misogyny of language — a guy is nice (an active choice), a girl is sweet (a passive state of being) — for the exact same thing.
But it's more than that.
When we walk on the beach, I feel free to fawn over a cute dog if I want to... or interact with a little kid who's playing in the sand.... And I'm forever talking to parking attendants, crossing guards, etc... always thanking them and wishing them a nice day... or strike up a conversation with women at a table next to us at a restaurant... things that I used to think "reign that in" and now I just get to be me.
And it reads as "sweet" — and that's fine by me.
