I'd yell at the bully, possibly point out that I know 114 pressure points in the human body, the last 14 actually overlapping major arteries and veins and if pressed with enough force can cause the blood to back up at the point and when it reaches the heart may cause cardiac arrhythmia which can lead to cardiac arrest otherwise known as a heart attack in the most non threatening way possible while muscling my way in between him and the victim.
Which element would you like to control, earth, wind, water, or fire, and why?
