'A friend recently described an incident with her father who suffered from progressively severe dementia, and who had almost completely lost the power to communicate. A televised act of worship was being shown and on impluse my friend said to her father, "Do you still pray, Dad?"
To her surprise he responded with a distinct "Yes".
"What do you say to God when you pray?"
"I say...(long pause)...Hello..."
No more was forthcoming, but no more needed to be said.'
