"No-- just don't say anything to him," my Mother states.
She is referring to one of many imaginary people around her that she talks to daily. The main one is a man she refers to as "John Doe". He pompously sits in judgement of her, taking her seat, using her pens. He gets most of the blame for things that 'go missing'.
I used to try to reason with her about "the people" when this was the first real sign of her Dementia that showed up besides her loss of balance. She first mentioned "the people" in Dec 2009. I argued with her about it.
