My 80 something yr old Aunt has a favorite chair that she likes to sit in at the beach because because she loves the view. I took a picture of the view from her chair, blew it up and framed it. She now can look at it in the winter from her favorite chair at home.
Find something that gives her that kind of pleasure,or if she likes a certain snack, arrange to have it sent to her once a month. She gets a double kick...getting a package and enjoying the treat.
That is a great idea too.
Everyone is so much more creative than I am.
