it reminds me of my great grandma she had dementia she remembered everyone else as someone else but she completely forgot me honestly it crushed me, we were so close. eventually she passed from parkinsons, and after she asked who i was i gave up talking to her. then she went into a transition, a coma, i believe. death transition as my parents called it. i never got to say a proper goodbye, but i am glad shes in heaven. purest woman i ever met, never got mad at anyone.
