I'm going to be really mean to someone that tried turning people against me
Why do you want to be mean to this person?
She keeps poking her nose in my business.
I understand why you'd be irked that someone turned others against you, but you said you were annoyed her? Maybe she had reason to talk about you in less than glowing terms.
I was just playing a game and if she doesn't get it, then it's her problem.
If it is a game that seems pretty rude too. You guys need to either make up or avoid each other you have a toxic relationship.
