Sad to learn of Hayden’s untimely demise. I’m not a sentimental man, I’ve never been overly emotional, and I deal stoically and quietly with death and tragedy. But I’ve always felt it is a double-edged sword, I never get the soul-crushing lows, but nor do I get the glorious highs… I am always merely content. Perhaps that explains why I cannot match such a brilliant piece of truly passionate writing. He went too young, but he certainly crammed plenty into his short time on this earth.. hats off to a young man with bags of heart.
