[Theory] If you live with older sisters or female cousins, you should sleep with a knife under your pillow

Your sisters are sick of seeing your ugly face everyday, even if you spend the whole day in your room, the fact that they share the house with a subhuman is painful for them. Remember they're in their prime reproductive age so every subhuman is garbage to them. One of these days, they might snap and kill you to get rid of you forever. And the worst part is that they won't go to jail cause they just need to create a story of how you touched them when they were kids or how they found out you're an incel and that's it. They would be heroes. Be careful.

Even Jesus said: "a man's enemies will be the members of his own household."
