Okay, two things you can try. One that I always wanted to do to my daughter but have never had the opportunity, is to record her and play it back. Sometimes I don't think people hear themselves. Maybe she'd be shocked.

The alternative, and probably a lot more fun, would be to imitate her tone and condescension when you talk to her. (Record that too because I want to hear it.) LOL

Oh! A third one ... Ask her why the fuck she wants to travel with such an imbecile.

I hate that she's invited herself along and then doesn't show you any respect.
