I'm going to visit my grandmother in her nursing home tomorrow morning for the first time. I haven't seen her in 12 years. She's had alzheimer's for quite a bit now. My question is: How do I treat her? Should I talk about the past with her? How do I separate myself from the fact that she probably won't remember me 10 minutes after I leave? This visit is going to be emotional for me already, so I need to know how to cope and deal in front of her. Thanks!!
