An acquaintance told me she'd been having a rough time, working three jobs as a single mother since her husband left her. Determined to cheer up her family, she planned a weekend trip. After working a long week, she started packing at ten p.m., figuring she could catch a few hours of sleep before their five a.m. departure. She asked her eleven-year-old son to start gathering his stuff; he didn't move. She asked again. Nothing. "If you don't help," she told him, "I'm going to smash your iPad." He still didn't move. As if possessed, she grabbed a metal hammer and whacked the iPad to pieces. When she told me this, I thought of how many parents I know who have fantasized or threatened this very thing, and here she'd actually done it. I laughed. "Yeah, my friends think it's a hilarious story too," she said, "but in reality, it was dark and awful." Her first thought as she stood over the broken glass: "I have to find a good therapist...right...now." Since turning forty a couple of years ago, I've become obsessed by women my age and their--our--struggles with money, relationships, work, and existential despair. Looking for more women to talk to for this book, I called my friend Tara, a successful reporter a few years older than me who grew up in Kansas City. Divorced about a decade ago, she has three mostly-grown children and lives on a quiet, leafy street in Washington, D.C., with her boyfriend. They recently adopted a rescue dog. "Hey," I said, happy to have caught her on a rare break from her demanding job, "do you know anyone having a midlife crisis I could talk to?" The phone was silent. Finally, she said, "I'm trying to think of any woman I know who's not."
