He said that for a while he could not comprehend what he'd seen on Sept. 11. He said he remembers seeing what looked like a stick figure falling toward the ground, but it was actually a businessman with a briefcase.
He said he could never really talk about his feelings from that day until he started interviewing other children.
"If they're able to talk about it, then I should be able to be more vocal about my experiences that day," Peters said. "I thought I was going through it individually. I truly felt more able to talk about it openly. Before I had a lot of emotions bottled up for a long time."
His mother, Michelle, said she was extremely proud of him. "He had to grow up really quick," she said. "It was definitely a trying time for all of us. Over a year of funerals."
She said he gave a voice to so many children affected by 9/11 who had no way to share their experience and helped himself as well.
"It's really been a healthy, therapeutic experience for him," she said of Peters.
