How many of you have encountered something unfair in the world and felt angry about it? (All their hands shoot up). And then how many of you came across something that you thought could probably help with that particular problem, something that would make the world a bit better, a bit more fair? (Almost all the hands go up again). Okay, last question: how many of you have shared this idea with an adult and been told that, although it sounds nice, your idea is impossible, it’s too idealistic? (All the hands shoot up into the air and the students look at each other knowingly, laughing and rolling their eyes).
