The same kind of people who have more than 30 cats, with 8 or 9 dead ones in the basement freezer waiting burial that won't happen until the city interferes.
You know, you think you can handle things but the stress keeps piling up. You're barely maintaining. Then an event happens, maybe a health issue or a financial set back and the next think you know the cat you thought was just fat has a litter and you can't do anything about it because the litter is in the attic and you have to be a cat to get up there, and the kid with mental issues won't shut-up and you end up tying them down just temporarily because right now Mommy needs some bourbon and Quiet and you had better provide the quiet in you know what's good for you! And if that means you poop your pants then poop your pants, gawdammit!! We’ll deal with it when Mommy can deal with it and that might not be until tomorrow!
A few days later you find yourself doing it again, only you’re screaming at another kid saying ”if you don’t like what I’m doing to Emily then you can either keep her quiet yourself or you can join her ‘cause I’ve got plenty of rope for everyone and if I have to tie up everyone to get just a few minutes of QUIET then everybody WILL GET TIED UP DO I MAKE MYSELF UNDERSTOOD?!!!!”
Months later the bondage routine has become routine, the kittens have been dealt with by catching them one at a time and clubbing them with a shovel, their tiny bodies disposed of one or two at a time. Order has been restored to a level Mom and Dad can cope with, even though they know secretly they’ve gone too far, which is why nobody can have friends anymore. Nobody but family is allowed into the house because all hell will break loose if outsiders see what is going on.
They don’t see themselves as bad people, just people forced to do things you and I won’t understand because we weren’t there facing the pressure they were facing.
