The first unit's listenig discusses an interview with psychologist Julia Parker about changing behavior over time for children.

When they are young children they are influenced only by their parents, they see the world through the eyes of their parents. As soon as children start going to school they start to relate to each other, with teachers and learn how to adapt to the environment. When they become teenagers they begin to want to join groups, because they need them to feel accepted and to develop their identities. In the class, however, there are always boys who will try to prevail over others, as they need to feel important and powerful. These guys behave like that because, in truth, they are not "powerful" and they are insecure about themselves. Since some guys start dating bad companies they start to behave wrong, become irresponsible, rude and aggressive. To solve this problem, parents and teachers must help the children, constantly offering their support and guidance, especially parents.
