Yeah, according to the nurse, the other one thinks the same.i would leave her sharing. the other lady may talk too much but probably thinks the same of your grandma you dont know. be guided by the staff as they see her all the time and am sure would tell you if issues are arising from the pairing. probably stimulates your grandma as well
It is funny because now we buy two of everything to share with her roommate, while the family of her does the same.
But I somewhat understand grandma, to be honest. She lived alone since 2002 since I finished school and went to high school and live with my parents + all of the neighbours and her friend dying before 2000
