Neighbour message that doesn't start a feud

The noise, the parking, the hedge: you need to say something and you'd rather not still be at war next summer. This writes a short note that opens with goodwill, states the issue as fact, proposes one specific fix and leaves the door open, with no blame. For the message you keep drafting in your head and never sending.
