Between seventh and eighth grade I went to a summer shop class where we worked with electrical wiring. I brought a pocket knife with me to strip insulation from wires, there being nothing else that worked as well. The teacher paid no attention to that horrible, dangerous weapon. Shockingly enough, it never induced me to even try to injure my teacher or another student. Clearly, the knife was spiritually defective.
I’m surprised you didn’t turn out to be a mass murderer with that background.
