What does his status as an Air Force vet have to do with anything in this story?
I imagine the guy got belligerent and could not respond. This is pretty common. If you are woken from a sound sleep, and have never been around an Alzheimer’s patient before it’s a reasonable mistake.
It’s a horrible shame for all involved.
Yeh but Alzheimer's parients usually only get belligerent if you try to force them to do something they don't want to do -- like take a shower, eat their meal, take their medicinne, sit still, go to bed, or when they want to go for a walk at midnight in the rain and cold and snow without any clothes on.
