Virescit Vulnere Virtus
If I say I have a headache, I have a headache. Lol.I have a headache means, I’m not in the mood right now, but don’t want to hurt your feelings with a blunt no.
In my case, Fine do what you want means, I told you what I wanted and you shot down everything I said, so....do what you want and I’ll do what I want.
In the case of the average woman, @Wally is probably correct. Lol.
