Water usage is probably my biggest. Living in a high desert, my wife and MIL see no problem with filling one side of the sink with hot soapy water to wash a few dishes because “that’s just how I’ve always done it”, to watering the grass and plants for hours. All of this makes me mental.
Damned if you do and damned if you don’t. Utilize the tools or you’ll end up unemployed.
In all honesty, I don’t think I could live with myself and, at least currently, think I’d rather find a new career path.
