There are a lot of activities that you can do in your leisure time. Some people are so tired of work that they prefer to use their free time just for resting and sleeping. Others spend their free time on their favourite activities.
For example, they listen to music, play their favourite musical instrument, go on a picnic, take a trip, go to the nature and enjoy the fresh air, hang out with their friends, go partying, go shopping, visit their relatives, spend some time with their kids and play games with them, read and write, watch TV, watch movies or cartoons, go to the theatre, surf the net, cook, do some gardening, etc. Some people like me choose sports to enjoy their free time. Among different kinds of sports, I prefer basketball.
