Would you ever tell your aunt off if she behaved this way? She is really rude?

Forget posting things about me on Facebook. If she wanted to say something rude to me, she had better say it to my face. I don't like conflict, but then again I don't like it when people talk about me behind my back. Sure it may turn into conflict, but why whisper in other people's ears? What is she so afraid of? A confrontation? I'm also saying, if she dishes S H I T out, then she better take it.
