The inner Karen wants to call the cops, but they will do fuck all to help the situation (if they even cared, which they don't). I don't need heavily armed and armored enforcers to tell my neighbors to stop being a bunch of dicks.
I wish we had a norm for this kind of shit other than complaining to an authority. I wish we were all mature enough to be able to handle this directly.
Maybe I'm just too much of a pushover. Someone with more of a spine than me would go over and have a friendly chat.
