Tham khao:
 I believe the best leisure activity for teenagers is any group activity. This could be playing a team sport or joining a hobby group or even volunteering. Firstly, teenagers like to feel that they belong to the group. Secondly, being part of a group helps teenagers make friends. Friendship is very important to teenagers. In addition, they will make friends with people who have the same interests as them. For these reasons, I think group activities are best for teenagers.
