Communication Breakdown

Most, if not all, problems are caused by misunderstandings caused by an inability to share enough information, accurately and effectively.

Even if you realize or accept this idiomatically, it's not so easy to follow. Often, without malice, and to heroically avoid information-overload, you think :-
1. Oh, but it's obvious.
2. That's not important.
3. It's not necessary for him to know.
... and you leave out bits and pieces here and there. You think, "Why bother them with these silly things".

These seemingly minor lapses in communication, slowly but surely, add up over time and lead to information-lockout. As Strother Martin observed in the movie Cool Hand Luke (also quoted by GNR in Civil War), in another context though, "What we have here is a failure to communicate"

And then you go ahead and do something based on the information you have which pisses off the other guy. Or, he would do something that is totally below your expectations. Voila, you have a flareup and quite possibly confrontation.

Communication breakdown, it's always the same.

As it is, it is really difficult to put things across. So before you leave out anything of your communication, think carefully:
1. Is it really so obvious?
2. Is it really not important?
3. Is it really not necessary for the other person to know?
