B.
you don't. you let others find out on their own.
STOP. Really just stop.
You really have this sense of superiority over others. You remind me of the "Twiight Zone" episode called ' 4o'clock' where his guy believes he is superior to all and calls the police and the FBI on people who he feels has done something WRONG and at 4 o'clock on a set day all those that are NOT morally acceptable will shrink to 4" tall. Well - the day and time comes and HE is the one that shrinks - not others.
YOU may feel the book was horrible - however it was published. Have YOU published a book? If no, who are you to judge?
SO WHAT if she tells people she's met celebrities!? WHAT business is it of yours to call her on it?? My God. Really. STOP.
I've met celebrities - Former President Clinton - his wife (urgh), Colin Powell, Madeline Albiright and others - I've met Casper Van Dein, Dina Meyer, and many others - who are you to call me on those??
Stop being the police of others. You really need to police yourself. You might soon find yourself without friends. Why? Because your "standards" are soo high that they don't feel like trying to reach up to them. Do you hold yourself to the same standards? Or do you already feel you are perfect?
