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.
If you want to be a member of Busines Suit Club you have to wear a suit. Membership has some benefits but the downside is less personal comfort.
