Henri Nouwen said it well:

There is a false form of honesty that suggests that nothing should remain hidden and that everything should be said, expressed and communicated. This honesty can be very harmful, and if it does not harm, it at least makes the relationship flat, superficial, empty and often very boring. When we try to shake off our loneliness by creating a milieu without limiting boundaries, we may become entangled in a stagnating closeness. It is our vocation to prevent the harmful exposure of our inner sanctuary, not only for our own protection but also as a service to our fellow human being with whom we want to enter in a creative communion. Just as words lose their power when they are not born out of silence, so openness loses its meaning when there is no ability to be closed. Our world is full of empty chatter, easy confessions, hollow talk, senseless compliments, poor praise, and boring confidentialities. Not a few magazines become wealthy by suggesting that they are able to furnish us with the most secret and intimate details of the lives of people we always wanted to know more about. In fact, they present us with the most boring trivialities and the most supercilious idiosyncrasies of people whose lives are already flattened out by morbid exhibitionism.
