Here's a memory that still haunts me to this day:
I could hear these wild nigglets from inside my apartment a whole hallway away.
I finally had enough and confronted them. Marched down to their dwelling and knocked on the door.
I could hear a wrinkly old she boon croaking through the door. "Yessuh?"
"I can hear your kids screaming through the whole hallway. You NEED to calm them down."
"Yessuh, Ah'll try, tank uu!"
It's been years and I haven't heard them since.
Much like the nigger working the lobby of my building, you can make niggers behave. You just need to confront them and establish dominance. It's literally like dealing with wild animals.
Use the camera in your phones to record their apeshit, hold their monkey asses accountable. Remain calm and speak low and deep. If shit escalates, call the authorities and show them your evidence.
And presto, your nigger problem will be dealt with, for the moment. Always be prepared.
