It's not the anniversary of his birth, or even his death, and he didn't pass away recently. But more and more lately, I find myself missing Philip Seymour Hoffman, the Oscar-winning actor who finally lost his long battle against drug addiction on February 2, 2014. These days, of course, I miss everyone – even people, like Hoffman, who I only saw on-screen. I've been feeling his absence more acutely than usual, though, over the past several weeks, and for reasons that are only partly professional.
