50 years old (Born on August 10, 1974)
Happy birthday to Rachel Simmons, the fearless author who helped us decode girl-world drama with "Odd Girl Out," and inspired countless young women (and parents!) through valuable wisdom in her follow-ups "The Odd Girl Speaks Out" and "The Curse of the Good Girl." Your insight into friendship complexities has made awkward teen years manageable—or at least humorously bearable—for thousands.May your special day be filled with joy, cake that's delicious enough not to share passive-aggressively, and friends that genuinely compliment without hidden agendas. Cheers to another year helping all odd girls feel wonderfully understood—stay brilliantly quirky!
