I remember my wife telling me this story about an ex's grandpa. Apparently, everyone assumed he was dirt poor, even his wife who washed their clothes by hand. Turns out he just hid all their money.

According to my wife, the kids were so proud of him when they discovered his horde of money after he died. It seemed really weird to her: "Who cares that his wife did miserable, back breaking work he could have relieved? MONEY FOR US!"
