as someone who was sole caregiver to a dementia patient the second picture also is damning..
Biden never speaks or looks at Obama all the way out. It is Obama who looks, smiles and speaks to Biden all the way out as if to say everything is going to be ok just hold my hand and follow my lead..
This is exactly what you do with a dementia patient to relax and reassure them as you try to get them where they need to go..
Watching the video, it looks like Biden has his hands full just shuffling his spindly legs forward. ,
