I asked sis about her hate for stepmom and she said that she thinks stepmom is a "annoying bi*ch", "stupid and irritating", blabla. She thinks stepmom changed dad. She did. But in a good way. He's happier, often in a good mood, he is more positive.. I think she's really good for him and I like him as he is now. He's happy and it feels better to be around him than if he's not,ofc.
