My grandmother was not a cheapskate, but she was certainly frugal, although the family agrees she came by it honestly. She raised 5 kids of her own during the height of the Depression, and they even took in a young girl whose family was really struggling.
Anyway, after my grandpa died, she would spend the winter months at my aunt's (her oldest child) house, a good 2 hour drive south of her home. My cousin told me recently of the time my aunt drove Grandma home at the end of March, and my cousin rode alone. They arrive and walk in to a blast of warm air. The furnace was doing a wonderful job, and the house was just toasty. Well, Grandma was just sick. The furnace had been running for 4 - 5 months in a cold Michigan winter in an empty house.
My cousin popped over to the next door neighbor to let her know that Grandma was back in her home. "Oh, I know!" the neighbor said. "Your sister called about an hour ago, and so I went over and turned the heat on so Ethel would walk into a nice warm house."
My cousin said, "You have just made Grandma very happy. She won't mind that the furnace has been on for an hour, it was the 4 months that upset her."
