Not to put too fine a point on it, but I think it was his step grand-daughter. That he fell in love with when she was 17, IIRC.
What's a man his age doing with a 17 yr. old? Come on "falling in love?"... Rubbish!..the guy was married...no less. He wanted to pay around with school girls and that's just the way it was....while keeping it in the family...what a complete dork!
