"Experientia docet" –Tacitus, Experience teaches . . . . Because we rely on our own experiences and knowledge when we attempt to understand others, and, vice versa, what we are relying on does not match their experience and knowledge. As a result, we "think we know" how to understand them, when in fact, we really have no clue. Unfortunately, we have yet to be able to directly share experiences, and, even then it would not solve the problem, because what is different between people is the totality of experiences, experiences of a lifetime. It would be like trying to connect one computer operating system directly to another operating system, it would not work well.
