Ask any Dentist, it takes a lot of upper body strength to remove a molar from a patient. That’s just one portion of one bone.
It seems incredible that this young woman was able to take a whole adult male sized cadaver apart, drain, package, haul, mop up (sort of) and burn some of the remains without stopping to ask herself:
“What in the hell am I doing? How did I get here after a minor disagreement? Whatever, I’m not going to think about that right now. I can’t undo anything. Plus, it’s near time to make dinner for the kids, and Joe’s father will be coming around again snooping, asking the same questions.”
You made me recall Scarlett O’Hara saying (in Gone With the Wind),
“Ill not think about that today, I’ll think about that tomorrow. After all, tomorrow is another day.”
