The night before my daughter started her freshman year at a new high school where she knew no one, I stared at the ceiling and made a few wishes. I hoped she’d like her teachers and make a new friend. Above all, I hoped she’d feel a little bit brave. They were simple, modest wishes. But after that first day of school, my 15-year-old came home in tears. Although she said she liked her classes, she’d gone to the cafeteria at lunch alone, changed her mind about eating solo, and skipped lunch to sit in the library.
