door-laches
A law dat prevents someone from hollering about a gate's being left unsecured if said closable barrier has been in said undone state for a long period of time.
As often as James Herriot had vehemently reminded Farmer Ripley about the broken gate that kept causing him injurious grief every time he had to open or shut it, there is little chance that said lazy farmer could bring a door-laches claim against said hapless country-vet for his indignant and aggravated protests regarding said deteriorated barrier.
