Recently I was talking to my mom and I asked her if she knew who I really am. She had a confused look, but after a few seconds she said (like she was asking), "You're my daughter...right?" I smiled and said yes. Then she said, "That's right you are. You're mom's oldest daughter!" She was confident in that, but the thing is I'm the youngest of 2 children and the only daughter, she was referring to her mother. So she thinks I am both her daughter and her sibling.
I'm not offended because even in her confusion I still feel her love for me. She knows she raised me because she told my husband after I left the room one day, "She's my girl! I raised her!" Something he said she was proud of. Still she remembers our childhood together, which of course is a confabulation. As her memories go, her mind works hard to make sense of why she feels the way she feels about me so I'm often included in her fondest of memories even when I wasn't really there. Her mind associates me with the good things.
I know before long she'll forget who I am completely, I just hope and pray she can still feel the love I have for her and she has for me.
