Cameron Thompson was once a little bully, picking on a kid who was different from himself.
"I struggle to make good choices at times," admits the California second grader in a video posted online, saying he has both ADHD and ODD (attention deficit hyperactivity disorder and oppositional defiance disorder). "Recently I made the wrong choice."
When another boy in school brought a Barbie doll to show-and-tell, Cameron got his friends together to tease the child, he says in the video entitled "Confessions of a Bully."
Cameron was caught and taught why bullying is wrong -- and it's a lesson he's clearly taken to heart.
"He asked me why he still felt bad (a couple months later) and I explained shame to him," Cameron's mother, Jessica Southard, told Banning-Beaumont Patch. "He then told me he knew how he could make it better. He asked me if he could start an anti-bully club at school."
Cameron also requested that the boy he bullied start the club with him.
More than 75 kids turned up for the group's first meeting at Tournament Hills Elementary School in Beaumont, Calif.
"We may be different, but now I know that's a good thing," Cameron says in the video. "We can bring our differences together to help other kids learn about bullying."
