My great grandmother had Alzheimer's and died when I was 11. When the last chance I had to see her at the retirement home came, I stayed in the car while my mother and little sister went in to see her. I didn't want to see her because she didn't know who I was anymore and asked the same questions over and over. Twenty four years later, I continue to regret that I did not see her (unknowingly) for the last time. And it was for selfish reasons!!!!! If I could only go back and change that!!!!!!!!!!
