My mom is 73 this year, pocked with Alzheimer's, haunted by ghosts and it can be tough to suss out from her description how many are phantoms of the mind, how many are figments of her imagination, and how many, if any, are visitors from some past Other Side. If they have a message for her, it must be frustrating. She won't remember it. "Well, your brother Michael's dead," she explained to my brother. This was after she and I had talked on the phone. I'm going to tell a story about her, and it's a Gentlemen's Agreement story where we're going to agree, thee and me, that I am telling you the truth.
