Thank you Locut0s, very moving letter indeed.
edit- this is something that leaves an impression and sticks in your head. Not to be effusive, but going through nearly losing a parent at 12 years old to cancer changed my perspective of life and death. There is no questionnaire that asks "how would you rate your death?" All that can be observed is by the outside looking in and to most it would appear disturbing. From what the letter says he went peacefully which is the most that many could hope for. Thanks again for the link.
