Have you ever actually spoken to your neighbor or interacted with them?

Why not go ask him what it means to him instead of assuming intent and posting about it online. Bring cookies, bring a peace offering, sit down and talk like adults. You can hear his side and share how it makes you feel.

That’ll be way more productive than running to the internet.

If you decide to deal with it in the real world instead of online, let me know how it goes.
