“Most people, when they talk about their childhood, a lot of times they talk about these great memories. My childhood was far from that,” says Simon. “I spent most of my early childhood locked up in a cage.”

When Simon was 2 years old, he was adopted by Sharen and Michael Gravelle. He claims that he and the 10 other foster and adopted kids were “treated like animals” and most were forced to spend time in cages that were 30 inches high, 40 inches wide and 40 inches deep and wired with an alarm to prevent the children from leaving.

“The best way to describe the cage was it was a structure of torture,” Simon says of the brightly painted wood chambers that were surrounded by wire. “During the day, most of the kids were allowed out of the cage except me. I wasn’t allowed out of the cage very much because they didn’t like me.”

Simon claims he slept on a wood floor without a blanket and often had to urinate in the “cage.”

“Sitting in that cage, I felt like a person that didn’t belong in this world, a person that was meant to be tortured. There were some times where I even felt like I deserved it,” the now 18-year-old says.
