How to Live with Someone You Hate?

Gray rocking and gentle parenting work in my experience. You're dealing with someone who has the emotional capacity of a toddler and who has never learned how to emotionally regulate themselves. This behavior is usually indicative of someone who is narcissistic or someone who genuinely cannot perceive the world past their own worldview. When using gentle parenting with these types of people, since they are acting like a toddler the goal is to treat them like a toddler but without them realizing that you're treating them like a toddler. Them: "Well in my day children behaved themselves or they got whipped." You: "It sucks that someone made you feel like it was okay to hurt you like that, especially when you were a child that couldn't defend themselves." Them: "Common sense just ain't common anymore/where the h3ll is your common sense?" You: "Common sense is taught, have you hands-on taught them how to do X the way you want it done so they know how later?" Them: "You didn't do it right! Either do it right or not at all!" You: "Practice makes progress, and they're practicing how to do it the way you like. If they never do it, they'll never learn how to do it the way you like." Gray rocking is saying the absolute bare minimum to someone you are forced to interact with. With people like these it's often common that they will say and do things to get jabs in and make sure that they're the last one to speak because they believe that it makes them win the conversation. So you let them. You don't say anything except for the absolute bare minimum. This is for when you don't have the capacity to try to gentle parent them at that point, or don't want to because it's genuinely not your job. Be warned though, because this route can cause absolute implosions on their part and make things worse before they realize they're not going to get a rise out of you and stop antagonizing you and things get better. Good luck. Look up things online of how to deal with abusive narcissists bc it sounds like that's what he is. And try not to fall down the rabbit hole that screams 'narcissists = abusive' because they aren't by default, and that's heckin stigmatizing and makes some narcissists later become abusive because they believe that's all they're destined for. Like how when you repeatedly tell a kid that they're a bad kid they become a bad kid. (I only say this because I fell down that hole and turned around and saw the damage it could do.)
