How could misunderstandings born of a lack of communication be resolved by the aforementioned lack?

It could happen. Persistence from one or the other. Someone has to give in or give up. Even if there are no agreements to resolve differing conflicts, there is no need to keep it a misunderstanding when both are able to explain thoroughly without the interruption of argument. That has to be important to you as well, otherwise it will just remain a misunderstanding and possibly a misrepresentation of what it was you wanted to say...if you care in the first place.

By always considering the context in which something is meant to be taken. If you do not understand the context, then ask what is meant by what is expressed, and clarify the lines of communication. It save a lot of unnecessary confusion.

Soon, there will never again be any 'misunderstandings', as we all evolve into empathic 'commun(ion)ication', completely transcending the inherent problems of spoken languages.

I have learned that when people do not want to listen to words, they listen to money. I wish you a huge fortune, not for you to be rich, but for you to see all those deaf cruel people crawl in front of you and at your feet once you have it.
