'Tell them to train the dog': Karen neighbor blames barking dog on neighbor's cats sitting in the window

It's important to have a good relationship with your neighbors because you never know when you may need them. You might be making a blueberry pie and need a cup of sugar and all the grocery stores in your neighborhood are closed for some reason. You might get locked out of your house with no phone and need a friendly door to knock on. You may have an all-night rager that's gonna get loud, so it's better if they're there too. All to say, don't jeopardize your relationship with your neighbors. 

But some folks have a hard time internalizing that. Sure, they might do something to annoy you, but one thing is for sure: passive-aggressive notes never work. They immediately set you off on the wrong foot, and they're hard to recover from. But that's exactly what happened in this recent Reddit story where a pet feud was sparked by a nasty neighbor note. Read on for details.
