During recess, the second graders were outside at the same time as my K kids. They're meant to stay on their side of the playground when the younger kids are out, but there's a small hill where the two fields overlap.
When we came out we were greeted by the sight of R, the older brother of one of my K girls, standing on the hill and shouting, "Oh yeah! Second graders in the house!"
Eventually, there was a confrontation, as these two siblings are always putting their hands on each other (with pushing or hitting at about a 3:1 ratio to hugging).
Another teacher intervened and sent R off. The girl in my class came running up to me and I asked her what happened.
"R was pushing me and knocking me down," she said breathlessly, "and then he fell down and he was rolling on the hill, and I was kicking him in the wiener."
