Sounds like the same exact lecture/”demonstration” I received as a mandatory part of college freshman orientation back in the late 1980s.
13 is way to young for this, the five years between that and 18 make a HUGE difference in terms of how to deal with nonsense like this. The group I went through “indoctrination” with recovered from the shock almost immediately and then came pretty close to giving the “instructor” an aneurism with our questions about Saran brand vs generic, whether Reynolds Wrap (OUCH!) or plastic sandwich baggies could be used if Saran Wrap wasn’t readily available when the urge hit.
It took the “instructor” several questions along those lines to realize that we were just scr*wing (figuratively, definitely NOT literally) with him and he ended up having a big tantrum over how we weren’t taking a matter of life and death seriously. The question that put him over the edge involved using Fruit Roll-Ups as a possibly more beneficial (better tasking, some nutritional value, less wasteful, etc) alternative.
So I ended up learning that ridicule is an incredibly potent weapon before I ever knew who Saul Alinsky was.
We should use this on homos and butches when they introduce their counterfeit spouses.
