Alzheimers

My dad  had wanted to drop some insulation off at my niece's house and play a round of golf with my brother.  My mother's home aide left at 2 and the other aide did not arrive until 3:00 or so.  He asked me to cover the gap.  Earlier my brother had called to let my dad know he had been working in the garden, lost track of time and would be late to meet my dad.  But with the Alzheimer's my mother understood that my dad was two and a half hours late.  She worried, I tried to distract her, but logic does not work with Alzheimers.  Diversion and distraction does.  When my dad came home, hot and tired after the golf outing my mother lit into him, "He was 2 1/2 hours late, he had a hot dog for lunch, he played golf at my niece's house.  The head knows that Alzheimers turns ugly, but the heart doesn't.  It is hard for me to sit and listen to my mother ridicule my dad.
