Right on. I had my now 22 year old daughter in Jeet Kun Do classes for 3 years. When she was in 10th grade, all of 5 ft tall, this boy came up and touched her inappropriately. She grabbed him, slammed him up against the wall and told him if he touched her again, she would beat the living crap out him. He did not come within 10 ft of her for 3 years.
She not only learned self-defense, but self-respect as well. Someone who is confident and self-assured will not be a victim of bullying.
