I've learned there is no point explaining or reasoning. They don't want to hear that. It doesn't validate their pov and that's all they care about. Just agree with them most of the time.
I should say it'll be a while before they're prepared to listen.
As for 'f*** you' well I drew a line about that phrase some time ago. It was usually uttered if I made a demand or was even slightly critical. Now I think carefully before I speak and sometimes it's best not to say anything.
