It wasn't that 51-year-old Alice, a former client, disliked her stepfather, Kurt. They just never got to know one another well because her 75-year-old divorced mother, Suzanne, had met him at a yoga class and married him a year later. Kurt was full of jokes and made her mother happy, but because Suzanne recently had been diagnosed with early stages of Parkinson's disease, Alice wasn't sure he would remain devoted as the illness progressed. I should be the one responsible for taking care of her, Alice thought.
