A girl and a boy were sitting beside me for the whole day long, and they kept playing with their phone and iPad continually and alternately. During the playing gap, they went to the canteen and toilet regularly. I could feel their struggle when they realized the time was passing quickly. Life is not easy when you want to fight against your instinct. As the day went to the end, they did nothing at all.
And I did nothing, too, but observed them all day long.
