My family spent the day at a funeral for a man at my home church. His 95 year old mother has been an adopted Nana to my sister and I for most of our lives and so we found ourselves in the odd role of pseudo family. Nana is suffering from Alzheimer's and so my mother helped her through the day. My sister and I spent time with her waiting for the family to get home from the graveside.
I wish I could know if Nana understood today anywhere in her mind. Somehow she knew my sister and I and told us often that she loved us and was proud of us. We talked about how many people were at the church ("Have I been to that church before? It's a nice one" Nana has been a member of that church since at least the 1930's) but never seemed to understand what she was there for. She asked where her Jim (the deceased) was today, did I see him? (I answered no, it was a closed casket). Strangest of all, when I left, she looked me in the eye, called me by name, and told me she loved me.
I love Nana too and maybe that's the point. I don't mind being single at all until I think of being old with no family left but maybe the lesson from Nana is that investing your life in people means you keep them. Then maybe they keep you.
