Can I ask how polite this is to say, in Latin? Would I say it to someone I had just met, at a garden party, or is it an abrupt demand, with a shade of "You stupid incompetent girl" associated with it? Taa!
I think "Livia, da mihi vinum" would probably sound pretty rude as opposed to "Livia, quaeso da mihi vinum". Probably depends on how much you're bothered by people not saying please and thank you (idk tho).
