"Okay mi- Vegetari!"
"Good, now you must do as I do. Follow my movements as soon as I stop said movement."
You run in 1 general direction, and take a sharp turn. You intentionally do this to demonstrate how to do the sharp turn recover. You scrape your feet against the soft grass, and press your arm against it to help stop your movement, Needless to say the boy was Impressed.
"Okay let me try AHHHHHH!"
He does what you do, however, as he was about to do the stopping motion, he trips.
"You need to improve your footwork boy."
