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.
You can buy night glasses to help with this bullshit. They don’t reduce the shine so much but they stop you from being blinded after being hit in the face with what is bright even for high beams.
