About this…
When I lived at my house, I stayed in the basement a lot during the day working in the office. I couldn’t hear folks knocking because I had often had loud music, and I was down in the basement.
The mail lady kept knocking on the door then marking me as not home. Over and over and over again. I verbally told her multiple times to ring the bell and not to knock, because I have an extra bell connected in the office and it’s super loud. She continued to disrespect me by knocking on the door and neglecting to push the button. Over and over and over and over again. Despite being told, and putting a sign on the door to push the button in lieu of knocking, and everything.
So… I installed a super bright narrow beam LED and a super bright diffuse LED next to the button and wired them to flash alternately. 24 hours a day. The super bright barrow beam LED I aimed directly down the street right where she stops at the other fourteen mailboxes on the way to mine. So the entire time she was on that street every day she had a super bright LED shining directly in her eyes from my doorbell button, a bit like a laser 
. (I lived on the turn at the end of the street) Then when she got to my mailbox the other LED was flashing at her the whole time, very, very obnoxiously.
Everyone in the neighborhood started referring to it as “the house with the flashing light” because any car driving down the street was blinded by my doorbell light.
fuck postal workers who can’t follow such basic instruction
That stinky bitch pushed the button after that… good thing too, because I had much more insidious things planned if she failed to push the button then…
…and that house is someone else’s problem now
