“Watch this,” I said as I walked over to the swings.
I sat down and began swinging with gusto. Within seconds a swarm of kids came over to watch and join in. After a few minutes, I hopped off and the kids mostly stayed.
The sub was impressed, but I wasn’t… my students follow my lead in most respects. Yell at them, they yell. Love them, they love. Swing for them, they join in.
