The ability to cry is when your body and soul agree on something.
It might even be a sign of health?
Niequist explaining it to her husband made me laugh:
And when we’re deep in the wreckage, I have to remind myself from time to time that it’s okay to cry. My friend Eve told me once that the ability to cry is a sign of health, because it means your body and your soul agree on something, and that what your soul is feeling, your body is responding to. I tell my husband that every time my own personal waterworks turn on. Sign of health, honey.
