Having the Correct Beliefs

In all relationships there's this idea that we need to first establish share shared reality by having the correct beliefs in both our heads, and then we can have a discussion about something else. But you and i think about it, we really can't even disagree unless we've got some shared understanding. Which isn't the same thing as having the same beliefs, right? Some of its belief but also it's that we are finding the same things relevant and salient. And so here's the final thing. I'm saying what we want is wise, right relationship with other people, not the ultimate true account of things about them.
