About the swimming thing. Pg 223 in Touched. Go to amazon.com; set up an acct (no nasty email barrage will follow). Search his book. Use the word 'payback'. Two options should come up. It's the second one. (Not all of the book is available there, but this part is).
Hope this is within copyright restrictions:
"some of the very last days when I had taken my father swimming...I accidentally lowered his upper body and head under the water....When I was sure he was okay, I put a smile on my face and said, 'It's payback time, isn't it?'"
Bear in mind, this is a memory he had of recent times; it was on the day his dad died, just after the coroner showed him into his dead father's bedroom to see his body. He said it was the cycle of life, with him holding his weak dad up in the water, just as his dad had done for him over 45 yrs before.
I just find that both chilling and informative.
