Ok so what I heard is that the boy had a messed up hand due to a bike accident and the coach wanted him to do push ups but he couldn't due to his messed up hand so the boy started to walk away and the coach walked over and started choking the boy because he didn't do push ups. it wasn't even gym that time it was hall time as well so he didn't need to do the push ups regardless so the coach just did before since it wasn't the only incident where he has done this to a student.
The kid got thrown out of class, then gives them thr bird as he walks back to class, then pushes the teacher twice. Nah, the kids wanted to play grown up, and he got treated as one. This is what happens when there is no full time man in the home.
