If you watch The Simpsons, Homer strangles Bart in many episodes. 2 kindergarteners, A and B, decided to act out that scene from The Simpsons. They took turns being the strangler and the strangled, seeing who could make the most realistic glottal sounds. They were having fun, and WEREN'T hurting each other. The teacher notices and sends them to the principal's office. A was then sent to the nurse's office and it was confirmed no damage was done to A's throat. B never got sent to the nurse's office and B's mother was called. Then B had to explain to their mom what S/HE did to A. A didn't have to do that. They were both doing the same thing.
