Bouvier followed the advice, left the job and returned to Washington after only one day of work.
When her mother married Standard Oil heir Hugh Dudley Auchincloss, Jr., Bouvier and her sister did not attend the ceremony, because it was arranged quickly and travel was restricted due to World War II.
Bouvier gained three step-siblings from Auchincloss' two previous marriages, Hugh "Yusha" Auchincloss III, Thomas Gore Auchincloss, and Nina Gore Auchincloss; she formed the closest bond with Yusha, who became one of her most trusted confidants.
On November 22, 1963, she was riding with the President in a motorcade in Dallas, Texas, when he was assassinated.
In her senior class yearbook, Bouvier was acknowledged for "her wit, her accomplishment as a horsewoman, and her unwillingness to become a housewife".
Jacqueline later hired her childhood friend Nancy Tuckerman to be her Social Secretary at the White House.
Soon enough, John Kennedy started to notice the value that his wife added to his congressional campaign.
Kenneth O'Donnell remembered that "the size of the crowd was twice as big" when she accompanied her husband; he also recalled her as "always cheerful and obliging".
