This whole incident was entirely preventable by one very simple action. The neighbor who called police could have just asked him to stop.
Yeah, it’s a bit odd to mow in my neighborhood that early, but he’s been doing it for 10 years. I can not fault the person mowing the law as he was doing it when he had available time and was avoiding the oppressive heat that is Oklahoma.
Seriously, if you have problem with your neighbors, just talk to them. It’s the neighborly thing to do. You might find out that they’re actually really nice people. Don’t use the police and the force of government when a simple, “Hey, can you wait till later, we’re trying to sleep inside and we can hear the mower really well. Thanks.”
That said, a neighbor that calls the police on me for something like that will forever hate me. If you run to the police instead of talking to me I wont ever give you the time of day ever again. Which around here also means most likely you’re shoveling the 6 feet of snow out of your driveway by yourself.
There is no reason one neighbor can’t talk to another. It’s why we have vocal cords, you don’t have to run to the nanny state every time you think your neighbor is a problem. Instead communicate and you might discover that he’s more than reasonable, and more than that, he might offer to mow your lawn too.
