When boys act out, get into fights, or become physically aggressive, we can"t avoid noticing their bad behavior. But it is easy to miss the subtle signs of aggression in girls--the dirty looks, the taunting notes, or the exclusion from the group-that send girls home crying. In Odd Girl Out, Rachel Simmons focuses on these interactions and provides language for the indirect aggression that runs through the lives and friendships of girls. These exchanges take place within intimate circles--the importance of friends and the fear of losing them is key. Without the cultural consent to express their anger or to resolve their conflicts, girls express their aggression in covert but damaging ways. Every generation of women can tell stories of being bullied, but Odd Girl Out explores and explains these experiences for the first time. Journalist Rachel Simmons sheds light on destructive patterns that need our attention. With advice for girls, parents, teachers, and even school administrators, Odd Girl Out is a groundbreaking work that every woman will agree is long overdue.
