She came up with the notion that two identical babies were born at the same time at the hospital; that two kids graduated at the same time at my high school; and so on. She often speaks to me about "my son Douglas" in the third person when talking to me and demands that I tell her where he is. I am now 68 years old (she's 88) and my hair is going gray, and my neck is starting to show signs of age. We live in the same place; we depend on each other. She can get very angry if I deny this notion, or if I insist that she show proof for her assertion--I could show her medical records and such, or even point out that the FBI has my fingerprints (I used to work for the post office). And this comes and goes--she will introduce me as her son Douglas to people we meet in public. I have given serious consideration to arranging conservatorship although I do not have the financial wherewithal for it.
