Every teenager(especially summer) think about how to spend my free time. Someone go to play football or computer games, other go for a walk with friends. Whether the time will spend on something useful or not, you decided this question.
As for me., I loved playing badminton in the past. It was very funny and usefully. Now I also play in badminton, but no so often as before. My mother often ask me to help,and, of course, I do it, because so I am learning and preparing for independent life.
