IIRC, the neighbor is also some sort of doctor or anesthesiologist, to me it sounds like they are competitive frenemies. Rand was burning tree debris too close to the neighbor's property line and the guy snapped. To me this sounds more like an a-hole living next door than anything else. Since there are 2 sides to every story, we don't really know which neighbor is the a-hole in this case.
