She may not be aware that the phrase has an origin with a different meaning. She may have also learned it that way and doesn't see the need to change. Some of us "highly educated" people can be arrogant.

My mom's mom had several sayings that were the result of miscommunication and misunderstanding. She referred to people that bed-ridden as "inblids". My mother told me it was years before she understood what her mother was saying.
