Barbara Bush is perceived as one of America's favorite first ladies. While in office, the white-haired lady often joked that she was "everybody's grandmother." As first lady, she was a strong advocate of volunteerism and worked to increase literacy rates in the United States. In 1989, she organized the Barbara Bush Foundation for Family Literacy. She also wrote two children's books, one of them jokingly written from the perspective of her dog, an English springer spaniel, and was appropriately titled "Millie's Book: As Dictated to Barbara Bush."
