You’ve never seen what dementia can do to a person. Or, just the general confusion that comes with age. I’m happy for you, honestly it sucks to watch. Someone who used to know everything suddenly gets confused on the way to a restaurant they’ve been to a thousand times. Forgets why they called, or even that they called you in the first place. And, importantly, have their opinions flip on a dime with no warning whatsoever.

This isn’t necessarily dementia, it can be caused by any number of things, ailments that younger people would brush off without a thought.
