I also vote for blocking her and telling them why. I don't think there's anything at all wrong with not wanting to know too much about someone's private life. And I personally would be kind of creeped out if a boyfriend of mine were having such a discussion with my 21 year old daughter and dropping hints about what he and I do. Kids typically don't want to know these things about their parents.
How does Choplet feel about her saying these things? Any idea?
