Reply #106: Teens often see adults as authority figures

[Nikia]

While they see usually see teens a few years older as peers.
Children tend to see adults as authority figures. They are trained to obey adults and believe that what an adult thinks is right is right. This is especially true of what they believe about adults who they trust and believe care about them.
Sometime in a child's teens or early adulthood, they start seeing most adults as peers.
A teenager who has gone through puberty but still has an authority like respect for adults that seem to care about them is in a vunerable position. Adults that would take advantage of a teen in this phase are immoral.
A teen a couple years older is probably not seen as a person in a position of authority or special respect. There are things that the older teen can do to take advantage of the younger teen that an older person would be less likely to fall for due to worldly experience. If the older teen lies or coerces the younger teen into sex, the older teen is being immoral. The older teen is not being immoral by merely participating in sex with the younger teen though, at least at the ages we are talking about. The adult is being immoral because the adult is being passively coercive by just being a respected person of authority.
