Presidents and First Ladies Trivia

[RJNorton]

Which First Lady wrote this to her social secretary:

I'm taking the veil. I've had it with being First Lady all the time, and now I'm going to give more attention to my children. I want you to cut off all outside activity - whether it's a glass of sherry with a poet or coffee with a king. No more art gallery dedications - no nothing - unless absolutely necessary.
