In French, we have "Nous" and "On". "Nous" is the easiest as it includes the orator in a group (but not necessarily the interlocutor). "On" is quite hard because it means "Some people, maybe one, that I don't know about". But "On" is also and informal "Nous" because used by children a lot, so even adults use it that way to. Plot twist, "On" can also be used to exclude oneself of a group that is known. Rich people will tend to use "Nous" as the exclusive version of "On". "On" is the most misused pronoun too.
