We don’t get many in this life. Genuine, true friends, in the deepest and rarest sense. The best of friends with whom you can talk about everything. Mark and I shared a rich, colorful history together which began in 1976 and crossed all borders of common interest. He had an enormously wide circle of friends, one wider than I ever imagined, until recently. I began to hear about and from people that I never knew, from his past who had heard about his condition and began reaching out to see what they could do for him.
