I am a graduate student who sometimes takes out DVDs at the library, and that's how I met Don. I didn't see him often, and in fact I learned his name only just now when I saw the notice of his passing, but I felt like he was an acquaintance, and I was very glad for that. He had a lovely energy, maybe because, as it seemed to me, he really didn't "sweat the small stuff." He was also incredibly patient, as he was with me on the afternoon of the day before he died, explaining a minor but complicated policy about picking up a DVD that he's just put on hold for me. Finally, I'll just say that I remember last year his telling me about a few excellent documentaries on Jazz, and how much it was clear that he deeply enjoyed them. They're next on my list, though it saddens me that I won't get to pick them up from Don himself.
