text: An activity is not must, it is usually something thought about doing for maybe spare time. It is an invasion of freedom, In a way, to make students pick to either play a sport, work on a yearbook, or serve on the student council without their will and some type of benefit. It could also effect their parents/guardian, if students are made to play a sport, because the parents/guardian would most likely have to drop them off and pick them up from games or practices. It should depend on what the students want to do and what they can do, no one should ever be forced to do something if they don't want to do it.
