Revenge

I grew up in a rural area and mailbox baseball was a thing.

And I had one neighbor who got fed up with it. Next time he had to replace his mailbox, he hired a welder to make one out of very thick steel, so it would look normal from the outside, but be strong enough to be basically bulletproof. A few weeks later, there was a string of destroyed mailboxes, and then his as the only one left intact ... with remnants of a broken baseball bat on the ground around it. Glorious -- and the neighborhood didn't have any more mailbox problems for years after that.
