To the best of our knowledge, our two groups recently came to an understanding with you regarding our relationship. We understood it to mean mutual ignorance - we leave you alone, and you leave us alone.
It seems that you have either failed to communicate this to your people, are of a different opinion, or simply do not care for upholding said understanding.
If it is a matter of failed communication, that can happen to all of us. A faulty receiver, and someone fails to catch the message.
If you are of a different opinion, I invite you to talk it out with us, either over comm or in person, in which case we can set up a meeting in neutral space.
If you simply do not care for upholding the understanding, please let us know. We will then stop upholding it as well.
