I was reading an article today in the New Yorker that a poet who has recently passed away (C.K. Williams) had written about a friend, fellow poet Galway Kinnell, on his passing in October 2014. Some of what C.K. Williams wrote symbolizes what many of us feel about Shannon:
"About the death of any one friend one feels sadness; with some, though, that sadness is tempered by gratitude, by a feeling of privilege to have been able to live in the world at the same time as the one who's gone."
Williams went on to write: "I knew Galway Kinnell for almost half a century, we were friends for a good part of the time, and that feeling of being fortunate to know him, to be able to be with him, never diminished."
