The key answer of exercise 4

Student A (Sandra McCullough)

1. People no longer know how to do nothing; they always want to be occupied in some way, therefore are drawn to the internet even when they would have real free time.

Student B (Gerald van Halen)

1. We define free-time activities differently now, and generalise a bit too much, considering for example all computer-based activities to be bad. Gerald thinks that if the activity is shared, it's good, even if it's an online game.
