I remember when I was a kid and tried to fool the school nurse into thinking I was sick. She was having none of it – before sending me back to class, she sized me up within seconds – and my friend who was actually sick looked at me with angry fatigue. Towards the end of Hirokazu Koreeda’s I Wish, a group of Japanese boys try to deceive their nurse in the same way. They’re more successful than I was because of how the nurse treats the boys. In Koreeda’s world, many grown-ups are happy to help kids preserve their sense of adventure.
