Whether these out of school activities are many or few, parents decide how many and which experiences their children will have. Adolescents, on the other hand, are becoming quite comfortable in the community away from home. They are mature enough to have a say in decisions about what they do and what they don't want to do. They want to pursue interests and activities of their own, not their parents' choosing. Adolescence is a time for exploring and experimenting with new interests or refining and expanding ongoing activities or interests.
Schools offer clubs, sports, etc.
Adolescence is also when individuals need to develop some independence from the family. Choosing one's own activities and dropping some pursued since childhood are ways to do so. Adolescents may even drop activities they like and still enjoy so they can make some choices themselves. Part-time jobs offer money and become increasingly available and attractive for adolescents. They find themselves having to make decisions about how to spend or divide their non-school time.
