I use to be the person who'd hit you if you hit her, but now I'm not because I learnt that, that person doesn't get anywhere but in trouble. So I turned into the person who gets the evidence of what your doing to her, watching the evidence fall into her lap as she builds up a case against you incase something unexpectedly bad happens to her, and if that unexpected bad thing happens she can unleash her evidence upon the world and watch the person who hurt her her fall and break, watch their mask fall of their face to reveal dark secrets and lies as she laughs behind her mask from the pain of her abuser. Does that make her insane? Or does that make her strong and smart? All depends on opinion and judgement, to me it's smart and strong but to you it might be cruel and evil.
