I've been there, it was 2005.
Grampa used to bring in wet clothes off the line from the backyard because "people will steal them"
Tried to set his son and daughter on a date, he had forgotten they were siblings. It's just keeps getting worse and you want to punch things, until slowly they just sit and stare out the window or at the wall, and continue losing weight to the point that you can not only see bone but ligament as well. They lie in bed, start communicating with people who have already died then they just never wake up.
I'm getting kinda emotional thinking about it, what's worse is that we'll all be there one day but probably more severe with all the weed/booze/general partying we've done in our 20's.
