Don't engage with them - they're baiting you into toxic conversation. When they start, simply say, "I'm sorry you feel that way" and walk away. "Don't feed the monster", my therapist used to say. My mother lived for conflict and disagreement. I spent way too many years and energy trying to change the dynamic with her. This one statement saved me a lot of misery. A toxic person can't argue alone. Wishing you the best!
