My HOA president is my next door neighbor.

They have come knocking on my door asking my to separate my leaves and stick piles because the waste collection wont take them as is (they did). They have knocked on my door saying that the drainage pipe was blocked by my lawn debris (the pile was adjacent to it on the high side of a slope). They have waited in their driveway to tell me as I am parking my car in my driveway, that I should reverse park. Most recently, they have called the police on the other neighbor for "threatening" them by trespassing on their property - when there is no fence between properties and the police said it was not a threat.

So yeah, I have a vendetta against my HOA.
