But also, how can a kindergartener choke an adult to the point they can’t breathe?
Because when you do not feel for other people you can go all in. Most people are not brutal and even unintentionally hold back against others. It is also really hard to defend against a child if you don’t want to hurt the child.
My neighbours kid broke one of his mother’s fingers at an age before he went to school (so he must have been 7 years old max). If you do not want to seriously hurt a child, how do you defend yourself when they won’t let go?
