history: I have just started taking care of my grandmother. I have just started taking care of my grandmother. That's very admirable of you. It feels like no one takes care of family anymore.
current: She has dementia and I am the last of her family.  I hate seeing her languish in the nursing home she is in.  Hopefully I can get her doing better. 
next: I am sure with your care, she will be much better off. I wish you and your family well.
