I gather twenty-two of my friends, and tell them that I have a sphere made of leather. The sphere, I tell my companions, is pressurized – filled with pure and ordinary air, blown inside it without the possibility of escape. I share with them my grand idea; we should divide ourselves in groups of equal numbers, and use our feet to push that sphere around. My compatriots agree, happy to joke and pass the time. As we prepare, one of these friends decides to make things more interesting. He comes to me and says that, since the area in which we will do this is very large, we should delimit one area from bouncing the ball to another, and suggests a symmetrical shape – a rectangle. We stand there, twenty-two men, kicking a ball to one other, and that itself is somehow fun. Other ideas arise as we begin this adult play...at least at the beginning.
