3. After Sean was arrested for breaking into a pawnshop, I began to wonder. Why did some kids from my neighborhood end up in trouble while most of us didn’t? I started out with a question: What causes young people to make bad choices? Now, after two year of research, I’ve arrived at the conclusion that there is no simple answer. There is no one reason why good kids go bed, but there are typical reasons. That’s because people learn their values from the people they associate with. So a very big reason for bad behavior is imitating one’s peers. But there are other important factors as well. Kids who get in trouble are often school dropouts. Also, kids being raised by a single mother are more likely to get in trouble than kids raised in an intact family. Substance abuse also plays a role, especially when it comes to alcohol and legal or illegal drugs.
