So people who have a lot of sex are worthless and vile....
You re entitled to your opinion of course but what she has done does not mean she is worthless at all.
She is making imho some dreadful choices but she is someone's granddaughter, friend and in the future she may well change.
My friend is now dead, in an accident, but she was a fantastic carer for her dad, regardless of going wild one night, i really don't know how you can be so blind to peoples other qualities or why sometimes they behave not as you would like.
Your reaction is one that would be valid for a child abuser or murderer....
You tone is also quite misogynistic too.
