Just something I was thinking about... after my grandfather passed away my grandmother with dementia couldn't understand where he went. She would ask us where he was and someone would tell her that he passed away and was in heaven but she just couldn't accept that he had passed away. She kept asking and it made me upset... She looked at me, saw my tears and I saw this expression of sorrow come over her. She stopped asking when that happened. I wonder if it was because she saw me upset or if she came to the realization that he was gone.
