My husband came to the youth theater rehearsal I was directing last night to work on some set pieces. He usually only works set on weekends when nobody is there, so his goal was to be totally inconspicuous. But the second and third graders treated him like a walking stim video. They were totally absorbed by his painting and drilling and clapped for him when he began or finished a task.
The children, in the middle of their scene, suddenly seeing that my husband is about to put the first stroke of white paint over a wall: WAIT can we watch please please please?
My husband is a somewhat large bearded man, too, so as soon as the kids walked in, I was explaining that I know him, he is helping us, and to not be scared if there was some loud noise.
Meanwhile the children are just watching him the whole time like :) :) :)
