You see the relationship between me and my mother and my mother to grandma (her mother) is very frail. Out of the blue my mother became very narcissistic and hostile to my grandma as well. My Grandma can’t explain it and me and my siblings can’t explain it either.
But yeah perhaps she just needs time to process this all. At christmas we all come together at my place (great idea, eh?) and perhaps the mindset has changed a bit, or it will a very difficult christmas.
