That's when you say something that's 100 percent honest and 100 percent respectful at the same time. More easily said than done, but well worth the effort, I've found. And it creates true joy in a relationship!
Is it hard to be 100/100? Most people are either very honest, to the point of being rude, or even hurtful -- or they're so careful to be respectful that they conceal what they really feel so they won't upset anyone. In both cases, the true intention of the message gets lost in translation.
