I'm thinking about cutting ties with my grandmother.
Why do you want to cut ties with your grandmother?
She's too old to understand me, she acts like her memories are the only things in this world.
It is hard to deal with our elderly relatives but it is not good to just ditch them. You will regret not being there for them in their last days.
No one's going to miss her when she's gone.
That's a hurtful thing to say, think about how you would feel if your grandchildren said that about you. Everyone grows old, and it's the responsibility of the young to look out for the elderly. Treat your grandmother as you would want to be treated when you are elderly.
