My grandfather passed away a few months ago in January, and he also suffered from Alzheimer’s. I remember one day someone mentioned they needed a tool for some house repairs. He overheard this and tried to bring them the tool from his shed. He kept bringing the wrong thing, and he could tell it was wrong and was growing increasingly frustrated because he couldn’t quite figure out how to bring the right thing. It sticks out in my mind because he seemed aware something was wrong, but was completely helpless.
I totally feel it when you say you lost him years before his death date. It’s terrible. My loss still feels so fresh. Thanks for mentioning your grandfather; it is a comfort to know someone else knows what it’s like.
