" Her happiness didn’t rely on her husband’s actions. And just because she didn’t walk around being ecstatic, it didn’t mean she was unhappy. He didn’t seem to understand that a person can function in the space between happy and unhappy. That space offered a level of calm and balance. It held an evenness, a place of moderation that allowed her to do her job and go home to forget some of the horrors she’d experienced that day. "
