We've all hurt one another's feelings. We've all had our feelings hurt. It's pretty miserable either way, particularly the later scenario.
The "hurt" feeling: a swift kick in the stomach, a tightness in the chest, our shoulders hunch over, our facial muscles collapse, our brow furrows as we struggle to understand what's happening...
Let's face it: it's unpleasant.
But it's also a fact of life. By that I mean, it happens. We do it, and it's done to us.
