My grandma was exactly the sort who'd inexplicably have two hand grenades in her refrigerator. She was a bag lady who happened to own a house and a good pension too but she had to be removed from her house as a danger to herself and others. No nursing home would tolerate her for long so she'd end up living with my parents in the master bedroom with her equally awful cat. I have scars on my body from the cat and scars in my head from my grandma. It doesn't help that I've inherited at least a quarter of my grandma's crazy. Fortunately there are good meds for that now.
Thankfully my grandma didn't pass her smoking habit on to me so I'll probably live at least as long as her crazy mom did. My grandma's mom was True Hard Wild West. As a kid I'd watch mesmerized as she'd cut apart fish, birds, and small mammals for dinner, sometimes still steaming with body heat, faster than I could follow the movements of her hands. My great grandma was also the sort who'd've killed any bad man who'd crossed her and then called her friend the sheriff-coroner to clean up the mess and file the proper papers. All four of my great grandmas were steely eyed women of the Wild West, skilled in the arts of guns, knives, and words that cut to the bone.
When I'm in my nineties I'll consider myself successful if they find something scary in my refrigerator. A plutonium battery or some glow-in-the-dark tritium, even a bit of antimatter would be pretty damned cool. But the testicles of my enemies, fingers, and other Berserker trophies, not so much. We're not pacifists in my family for any noble reasons, it's mostly by necessity.
