I know how bad this sounds, but fuck this dude pre-re. You mean an older supposed man can’t subdue his crazy, busty sister for 5 years??
Don’t give me that equality bullshit, there are no words for that level of soft. This is worse than that bullshit about female classmates bullying a male student. To be clear, I’m not saying you should haul off on a woman because you’re too stupid to deal with her shit talking you, but if someone’s or your life is on the line, you treat it as any other threat. Honestly, you shouldn’t have let it get that bad in the first place.
At least now there’s a semi legit reason to be scared of her, but make no mistake, I’d die before I let some shit like that happen to me.
