“Darian moves down my arms—focusing on the ulnar nerves and my carpal tunnel wrists and exhausted hands, lifting each finger out like we’re co-conducting a waltz. One winter, years ago, when I was the saddest I’ve ever been, I sat across from a beautiful woman at a coffee shop and she stretched out her index finger and touched mine and said: Zap! Keep going. And sometimes when I am very low, I can still feel her zap.”
