rdgrad, there are a variety of personalities out there in the world. Some of them are immature like that. There's nothing you can do to change those kind of people. If they tell you that after an argument, don't take it personally because it's more about their severe emotional immaturity. Nobody mature responds to a fight with that retort. That's the equivalent of sticking out their tongue at you. Like a child. Be done with those types of people. They aren't worth the effort.
