I was introduced by some young guides to "their school", which was just having a break. And no, the kids didn't go for the healthy apples their mothers gave them, but for the sweets the janitor was handing out by the dozen.
I have often visited schools and it is funny how kids will just bring you in, and how you are accepted by the staff even if, as I did on this occasion, you keep pressing the camera to your eye and keep shooting.
