"...a choice had to be made when your husband said something unkind. Specifically: be cruel, be strong, or sulk. 'Be cruel' by saying an unkind thing back. 'Be strong' by choosing not to mind. But to do this, you have to use up a piece of your love. You have to shave off enough of the love to forgive. After a while, the piece might grow back, but sometimes not. And if you shave off all the soft curves, you'll be left with a sharp-edged love. 'Sulk' by sulking. Sulking is simply delaying the choice to be cruel or strong."
