After my dad died and my mom’s worsening dementia forced her into a care facility, it fell to my sister and me to clean out their house. When we walked inside, it was like uncovering an intact archaeological site. My dad’s closet was still filled with his fleece jackets and golf shirts. Inside the pantry, opened bags of potato chips and crackers were sealed with clips. I expected my mom to walk into the kitchen, grab the half-used bottle of Windex from the shelf and clean the table.
