A War with our Neighbors

We have some neighbors that just moved in this year. They are very mysterious, and they never show their faces. Recently, while my sister and I were home alone, our parents called asking if Ginger, our dog, was outside barking. We responded with the truth that she’d only been out for a few minutes. When they got home they told us how our mystery neighbors had posted a complaint on Facebook that was sent to everyone else that lived around our little pocket park. It was about Ginger barking, and apparently other neighbors had been complaining too. We asked our other neighbors, and they had not been complaining. My dad sent a passive aggressive email to her to contact us directly next time, but she just sent a rude email back. We are now at war with our neighbors.
