FOR months Jimmy had noticed his daughter, Tessa, inexorably pulling away from him. Like a boat from a dock, he lamented. It wasn’t just the physical distancing that upended his heart, but the eye-rolls, the scoffing, the insolent glazing over. One afternoon, he walked in on her dancing, filming it on her phone. Overcome by pettiness, he began dad-dancing in the background. He didn’t get the reaction he’d intended. Instead, Tessa guffawed and copied him. Later they sat thigh-to-thigh, watching it back, and each time she laughed she placed her hand tenderly on his shoulder.
