so, being a fairly well-off guy from the 1810s who regularly hangs out with sirs, attends fancy parties, and actually met the king one time, Strange has all of this manners shit in the bag. He'll gladly help out and teach people how to tie a cravat, how to waltz, how to formally introduce themselves to an important person, which fork's the salad fork and which isn't, how to be polite, and so on and so forth. I'm up for threading or handwaving these, but I'm totally up for characters hitting Strange up for ✨ fancy lessons ✨

(this also might be an attempt to distract himself from the fact that during his canon update, he got stuck in a tower of darkness himself and that he's NOT TOO PLEASED and KIND OF PARANOID about this whole realm of twilight thing)
