I've always suspected that TLC (Theresa, Lynda, and Corky) were smart, capable women. They just needed Robin Williams' voice in Disney's movie, Alladin, to teach them the concepts to... hmmm, "get along" is too strong... perhaps "not annoy" is sufficient for now.
Concept #1 - Thou shalt not maintain an illegal nonconforming use on a residential property.
It has taken a lawsuit to finally penetrate their insular* half-acre world with that loud and clear concept. They have always claimed that TLC Catering and Commissary was a legally grandfathered business, but the facts prove otherwise. Their dismissive, contemptuous conduct against neighbors' interests since 1987, and their deceits** foisted on city and county officials since at least 1993, cannot be turned to truth merely through constant repetition.
"A lie is a lie even if everyone believes it. The truth is the truth even if no one believes it."
Concept #2 - Laws and ordinances represent MINIMUM standards of behavior.
Laws have to be written because some people simply cannot figure these things out for themselves. Laws train people to understand and adhere to principles of behavior, which eventually allows them to govern themselves, giving offense to no one.
Something... someone... somehow... finally penetrated their insular* half-acre world with the teensiest message that 8:00 a.m. is the earliest time that (wo)man-generated or machine-generated noise is allowed in a residential district - and even then only for reasonable periods and purposes. Imagine that! ...and for all these years they have claimed immunity from any regulation they deemed contrary to the illegal operation of their business, including their supposed "right" to make noise at all hours of the night and day with the commercial deliveries, the Ice Bucket Brigade, and now the yard radio.
Concept #3 - Your "right" to make noise STOPS at the fence line.
(OK, they still haven't internalized this concept.)
In other words, noise STOPS at the fence line. It is NOT your "right" to dump your noise pollution garbage onto my property and into my house.
Good neighbors completely understand that noisy activities, which normally occur on residential properties, such as mowing the lawn, using other powered equipment from time to time, children having a party or splashing around in a pool, or any number of other natural sounds - such things are rarely a bother. (Indeed, they are disturbing if missing.)
Problems arise between neighbors when industrial, commercial, and other nonresidential activities create nuisances - lights, dust, noise, vibration, smoke, etc. And the biggest problems arise when the offense runs one-way.
Good neighbors also completely understand and apply another rule:
Concept #4 - By their fruits ye shall know them.
Gospel of Matthew, Ch. 7, v. 17, "Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit."
