Sometimes what helps a person heal is to help others, to give & recieve comfort. That's what support groups are all about.
The way I see it, George can remain in his home, drink in hand, full of sorrow & pity ( and I wouldnt blame him for that) OR he can be there for others because he knows first hand, in his gut, how God awful this feeling is. Isn't that what makes Tim Miller the compassionate person he is who has made it his life mission to to help those who have loved one's missing? I am not saying GA is a TM, I am just saying we never know how any event will change our life. If this family takes comfort from a kind word or hug from George, than God Bless him.
