My grandmother and grandfather were both very strong headed and they would argue quite a bit. I remember watching one argument that went back and forth for a while until my grandmother finally said something that stopped the argument without ending it by winning or losing the argument. She said something like, “Well, okay,” and shrugged it off.
I learned that at any time you can stop arguing and just shrug it off as, “Different people think different things.” Sometimes it’s better just to get on with your life, especially if it preserves a valued relationship.
