If you're being harassed by a chronic bully in your building, you may want to start knocking on your neighbors' doors. "Bullies won't stand up to a crowd," notes a Habitat Magazine column titled 'When Residents Attack.' "Someone who disrupts meetings might ignore the president's order to sit down, but may respond if five other residents say likewise. The resident who shouts epithets in the parking lot will stop if other residents declare that this behavior won't be tolerated." (Habitat.com)
