New York, January 7 : Former U. S. President John F. Kennedy's daughter Caroline made a real gaffe when she interacted with the press for the first time at the tender age of six, says a book.

`Rethinking Kennedy: An Interpretive Biography' by Michael O''Brien reveals that Caroline was approached by a group of reporters while she was running around the White House.

One of the reporters asked her what her father was doing, says the book.

"Oh, he''s upstairs with his shoes and socks off, not doing anything," the New York Post quoted her as having replied to the question at the time. (ANI)
