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.
“that’s just how I’ve always done it” is the worst when it’s used as an excuse to avoid putting effort into personal growth
Nobody in your life agrees with you? You gotta get out of that toxic environment.
