It’s all very well to cry for any number of reasons, including the fact that sometimes you simply need a good cry. And since a lot of the reasons for crying occur largely in your head—which is not to say that they’re not real—it usually helps. Perhaps the world won’t have changed for the better after five or ten minutes spent sobbing into a pillow, but at least you won’t feel quite so much like crying. The red hollow under your breastbone is emptied out, and things can be faced with more resolution. (And a swollen nose and itchy eyes, of course, but you can’t have everything.)
