Heather Christle is extremely good at gently reminding us of things we know but don't verbalize often enough. Even the observation that crying is the first thing we ever do helps to reframe an activity that most of us don't actively enjoy. I appreciate this book because it treats crying with nuance: not simply glorifying it as cathartic, or focusing on the discomfort in crying. Unsurprisingly, this book is often sad, but also scientific, oddly funny, and sweet.
