I’ve recently moved into a row house in an urban setting. Recently, my next-door neighbor sent an email about HOA business to everyone in our row of houses, and I discovered that she has me in her contact list under the alias “LOUD neighbor.” I’ve thought long and hard about whether it’s possible that I’m too loud. I do have two grade school–aged sons, but they are in bed by 8 p.m. We don’t play music. We don’t have a dog. We don’t bounce balls against the shared wall. We don’t have parties. We do not have loud domestic arguments. … Should I confront her? Should I buy my sons a drum set?
