There are a few people out there with whom you fit just so, and, amazingly, you keep fitting just so even after you have growth spurts or lose weight or stop wearing high heels. You keep fitting after you have children or change religions or stop dyeing your hair or quit your job at Goldman Sachs and take up farming. Somehow, God is gracious enough to give us a few of those people, people you can stretch into, people who don't go away, and whom you wouldn't want to go away, even if they offered.
