Psychologists argue that all teens, at least, do wnat someone in their lives to set some level of limits for them. This does not imply that they want all of their actions to have limits, but it does mean that they want some limits imposed on them.
The idea is that teens are not always sure of what they should and should not do in their new lives. They do not always feel confident that they know what is right and they can be overwhelmed the range of choices that they now have to make. For this reason, they want to have someone help them lay out limits. Once they have those limits, they can feel more free to explore within them.
