I feel somewhat of an imposter here as I only met Cal once, a couple of weeks ago, at 3am as we were passing a phone and a desk from one to another. But I thought about our conversation a number of times in the ensuing days - the vibrancy and sharpness to their mind  and the absolute unconditional thoughfulness and kindness of spirit.  So I feel very lucky that I had 10 minutes with Cal. With love, Mark
