A recurring theme in "Becoming," the debut memoir from former First Lady Michelle Obama, is the physicality of her most powerful emotions. When her family was elevated to a fabulous, unimaginable height, she focused on normalcy—a good education for her daughters, date night with Barack, two dogs to dote on. Barack is the dreamer, the idealist, the leader. Michelle—entranced, overwhelmed, concerned for her family’s safety, and finding comfort in a McDonald’s burger and a Target run—is more like the rest of us.
