Dad was notoriously cheap.
When my mom started going through menopause, he would get upset because she'd leave the bed and go sleep on the couch with an open window. He said her hot flashes were all in her head. Then he was diagnosed with cancer and the chemo gave
him hot flashes. Lo and behold, a window unit air conditioner appeared in the bedroom.
What a jerk. I was mad for her, but she was just thankful for the AC.
