It's my father's sixty-eighth birthday. He was a beautiful, generous man, who believed in relativity and the fundamental decency of humankind. He's been dead a while now, and I try not to think about him too often, so great is the gap that he left. I am still the luckiest boy alive to have been loved and raised by such an ordinary, warm-hearted fellow. Snot and tears prevent me writing more, but there's not much more to say. Imagine your ideal best friend and then recast him as your father. That's how privileged I was.
