What is an age-appropriate skill for a fifteen-year-old?

Using the telephone to call a friend is considered an age-appropriate skill for a fifteen-year-old because it reflects the developmental milestones typical of adolescents. At this age, teens are generally gaining independence and developing social skills, which includes communicating with peers on their own. This activity not only fosters social connections but also enhances their ability to manage conversations, make plans, and express themselves.

Conversely, reading a book independently is a skill that many young children and more mature teens may possess, but it doesn't specifically highlight the independence and social interaction typical of fifteen-year-olds. Cooking a full meal can vary widely depending on prior experience and training but is typically something developed over time rather than an expected skill at that age. Finally, driving a car generally requires a legal age of 16 in many places, along with the prerequisite supervision and testing to ensure safety on the road, making it less appropriate for an average fifteen-year-old compared to the social skill of using the telephone.
