In response to that email from the grieving father, I suggested a few games, one of which was the Frog of Enlightenupment. He writes back:

Thanks for the quick reply and the links. I already searched on your site and found an article http://www.deepfun.com/grief.html that I enjoyed reading.

I was a little startled at the first link "The Frog". My oldest daughter started collecting frogs a year ago, stuffed animals, jewelry, statues, etc. (no live frogs yet). I can't wait to show her that link. Also, in the first days after the accident a large frog suddenly appeared on our deck pond. We usually get little tree frogs but this one is very unusual. It is usually there in the mornings and evenings, and somehow has been a source of comfort to us. There were also some strange coincidences regarding the frog as well as other animals with close friends of my wife. Not only that I just noticed that the song I'm listening to is "2 Frogs" by Five For Fighting. Can you hear the Twilight Zone theme start playing? :)
