i had a sister-in-law back home in cullman who was roughed up by her partner when he got drunk. she waited till he went to sleep and fractured his skull with a cast iron skillet (the skillet was unharmed, thankfully). he was in the hospital for a goodly while. when he came out of the coma, she told him 'just remember, you're bigger but you gotta sleep sometime' - he never hit her again.
he did go out and get drunk tho. she decided to lay down the law. next time it happened she told him he'd best never do it again. he said as he lay in bed 'and what you gonna do about it?'. she put two rounds from her S&W into the headboard either side of his ears - took him two years before he went out drinkin.
sadly his kidneys failed, he needed dialysis 3 times a week. their insurance bought them a machine and had her trained to put him on the machine to filter his blood. she reminded him how fast he would bleed out of she disconnected the return tube, and how slowly he'd die in agony if she didn't scrupulously disinfect the device. he became a model husband. an thus endith the tale.
wimmin may be smaller, but god made up for it by making them meaner.
p.s. - i also remember an argument i had with my shortly to be ex-wife which showed me graphically why they put guards on combat knives and why csi always looks for the perps blood as well as the victims in a stabbing.
she tried to stab me with a steak knife and missed as i was trying to get the heck outta the kitchen. so instead she hit the wall and her hand slid down the grip onto the blade. she was a lot nicer as i drove her to the hospital. (20 stitches). i still have the steak knife. it's one of my favourites.
