Although boys often bully in a physical way, girls’ style of bullying tends to be more indirect. Girls bully by creating a hostile environment for their victims; they may spread rumors or exclude their targets from activities. “In a way, it’s easier [to do] because it’s not direct,” Charles Williams, clinical psychologist, says. And because it’s so easy to spread a rumor or make threats, mean-girl bullying can do a lot of damage — without the physical clues for parents to pick up on. If your daughter is acting sad, depressed, and moody and is reluctant to go to school, talk to her about bullying.
