Your friend situation is like a sexual harassment case at work.
It is always the other party that feels comfortable or not to throw a sexual harassment case towards you.
In your friend's case, it is all up to the child to decides. If it was up to me, I'll take your riches and plays with it but in my mind, I still don't even know the message is being given here. If her idea of buying her missing time and she doesn't recognize it then that's a failed mission.
You may not want to her this next true story. A wealthy white guy at the casino was playing at the table and the dealer is an asian chick. She took a loan from dude for $2,000 with a 10% interest compound weekly. When she can't make the payment, he told her to go to his house and they can discuss things over. He was able to conned her to have sex with her. In her mind, she's thinking that after sex, the debt is fully paid right? Not quite, he stood up and told her she still owes him $2,000 and if she can't pay next week, come on over again.
The game of a loan shark and female gamblers who takes on loans are what I called "sick biatches"
Push and pull, the game is still played both ways. Your friend's daughter will take them riches and may feel nothing in return.
