You can start this essay with a great story about a conflict between parents and teenagers over rules. What would be a really good strategy for writing on this topic is to point out that both sides really want what is best for the teenager and are wanting them to grow up to be a responsible adult, but they have different means for how they think that should happen.
Here are some other topic ideas:
1. How can parents best adjust their rules to let their children learn adult responsibilities and choices?
2. How should teenagers most effectively talk with their parents about changing rules?
3. What is the difference between rules that keep teens safe and rules that are not really necessary?
4. How can parents best instill their own values on their children?
