The Olympics Are Less Complicated

I'm looking out an office window that overlooks a primary-school playground, killing time while I wait for Nortons to be updated on the Mac that I'm using. A class of very young kids is outside on the half-size netball court with its teacher. The kids have been divided into four groups of about eight people each, and are lined up in four rows to have races to the other end of the court and back, one person per team at a time, in a sort of tag-team event. The teacher says "Go!" and the first kid in the second, third and fourth rows starts running to the other side, as does the first kid in the first row, along with four other kids that had been standing in line behind him. The five kids from the first row run across the court in single file, not breaking their row order, until the teacher stops the race and re-explains how the game is supposed to go.
