Also Daddy please love me. Please forgive me, next time I'll be better".
I worked on a book (editing) by an incest survivor who finally took her father to court after she grew up. This is EXACTLY the kind of thing she'd write or say...she was obsessed, as a child, with pleasing her father in every way possible to keep him off her. The sadistic man would punish her for the slightest infraction of his arbitrary and ever-changing rules by raping her....it started on her first day of school, when she was six.
In that particular case, which became rather famous for awhile, the father could be brought to court years after the incest because he'd started again on one of his granddaughters, and that brave little kid testified and put him in jail.
Anyway, if Danielle wrote this "apology" in her diary, I'm convinced she was an incest victim. Actually, the first time I saw her photo, I got the impression that she was an abused child. Maybe Damon loaned her out to a friend, and the friend got rough. This is not a far-fetched idea. People like Damon do things beyond imagining.
