Is there an official manual for Catholic Social Etiquette?

As in, how to get a sense if I'm overspiritualizing casual everyday moments/ conversations or actually rejecting genuinely inspired attempts to maximize the 10 commandments, reflect on moments of grace, if I think I see God interacting with someone then I intentionally act in a way that does not contradict that aiming for humility, etc.? Have any saints or theologians written on this?

(In a way, being scrupulous but in the opposite direction. A very clear example of people over romanticizing the priests and not acting "normal" specifically when around them.)
