I've been participating in kid's sports day.
It was a lot of sitting, very little participating or sportsing. But a lot of people-watching.
Other classes walk in an orderly fashion, and they have several parents that joined today. Kid's class are chaos goblins from a formation viewpoint when walking together, and I'm the only parent that joined. But they get to where they're supposed to.
Kid's class act both active and mature in their friendship and behavior toward each other, others are more passive and childish. It really stands out, out of fourteen classes, six years.
