All parents know that one of their most important tasks is to prepare their children for an independent life,but any parent can tell you that it’s hard to let go of your children.That balance between keeping your children safe and allowing them to learn from their own mistakes can be heartbreaking.Years of experience means that parents often do know best,but on the other hand,the young,being less bound by tradition,are often more creative,more able to find new solutions to old problems.Revolutions are led by the young.

Good teachers make the growth of critical (批判性的) thinking easier in their students,only to find that this can lead to a questioning of the teachers’ basic beliefs.Schools encourage parents to become involved,but are often embarrassed when parents have reservations about some of the educational methods being used.Governments encourage unimportant groups to empower themselves in order to participate fully in the development process.And they are often surprised when the new leaders of these groups turn around and attack the policies of that same government.The rebellions (叛逆的)young and the newly unimportant groups are important in social development.They are not necessarily representatives of those they want to represent or not realistic in their demands,but their voices must be heard.

Good parents know that just forbidding particular behaviors does not prevent their children from finding ways to engage in these forbidden activities.Indeed,sometimes the forbidden fruit is more inviting,just because it is not accepted by authority.Parents must work with their children to educate them on the facts,know as much as possible about he lives of their children,provide a good example,encourage more wholesome activities but also support their children when they don’t follow what is expected of them.But the most important point is that they also need to learn how to let go.
