Both of Mr. Saddi's parents married people who didn't want kids. His mom married her 5th husband when he was 12, his dad married an equally charming drunk the next year. He ended up "staying" at his neighbors for the next 7 years, an elderly couple with no kids of thier own. So he lived next door to his dad, who still technically had custody.
When he took his child psychology classes to become a teacher he came home "hey honey did you know I was neglected as a kid", it had honestly never occourred to him untill then.
