I disagree. Forgetting your keys or putting your glasses in the fridge are signs of distraction, not paying attention to what you are doing but probably thinking about what you are going to do next. I’ve been doing this since I was a teenager, many, many moons ago. Altho must say I haven’t done the refrigerator-keys bit. So far! :)
Dementia is when you don’t know what your keys or glasses are for.
I just checked your home page. You have my very favorite photo of George Bush! His heart and soul were on display that day. Unfortunately the current occupant doesn’t have much of either!
