It sounds like a problem for sure, with pseudo-greenies.
I do have to say that I was unhappy with my old neighbors who sprayed pesticides and weedkillers right up to our garden fence in a brisk wind blowing our way. We don't use pesticides or weedkillers, and never on our garden. They had an absolutely manicured lawn. That's not our neighborhood, which has gardens, huge lots and some with native wildflower plantings. It was irritating to me when we would stand in our yard and have to go inside when they were liberally spraying every square inch of their property and a bit of ours.
Maybe that has them being so unfriendly(?). People with asthma (me) really have issues, and when the wind is brisk it can really be bad. Nice lawns are important to some people, especially in suburbia, but I don't want overspray on the food I'm eating. So maybe there can be a compromise. We like all of our neighbors now. We keep to ourselves and our own yards and leave everything alone. But if someone needs help, they jump in to help.
Wasn't it Robert Frost who said "Good fences make good neighbors"?
