The squirrel was jerking back and forth uncontrollably in the grass. I was really worried about it. Had it got caught in some wire or a line?
I had thrown a thin branch into the grass from the garden and the squirrel was grabbing it and twirling under it and at one point it jumped straight up, at least half a foot, into the air.
And then I understood. It wasn’t caught or hurt. It was having fun.
