I suspect that the single greatest assumption we make concerns the stability of our relationships. We busy ourselves with those things that cannot speak because we fear they'll go astray without warning whereas we fully expect that the people in our lives will voice their concerns and do so before matters sink into a crisis.
That is a major mistake. Fail to communicate frequently and in detail with your close associates and an unpleasant surprise can be practically guaranteed. What you may see as trust they may regard as neglect or indifference.
Overcommunication has its downsides but it tends to smoke out problems. Someone in your life probably needs your attention right now. No news is not always good news.
