I'm so glad I took the time to visit him a couple of times in the Care Center when I was here on this trip. I only expected to stop by for brief visits, but ended up staying close to two hours each time. (Hey, I did say he was a great guy -- it was such a pleasure talking with him.) And his wife Cecile is as much a treat, who after so many years of marriage knew when to let Sid be Sid and simply let his outgoing humor just slide off her back with a bleary shake of her head and a knowing roll of her eyes. (Oddly, though he was so funny, he only really knew one joke, which he apparently told with great relish whenever prompted for probably 30-40 years. Watching Cecile's patient and loving weariness at hearing him tell it...again...and again was a joy.)
The last time I saw Sidney, I said I looked forward to seeing him when he got back. He quipped that he hoped he did, though it was clear he wasn't just making a joke. I wish he was. He was such a good guy.
Here's a video of Sidney on C-SPAN. I hoped to embed it, but they only provide a link. It's from a December 5, 1989 conference titled, “What Can be Done to Improve the Presidential Debates the Next Time Around?” (A bonus treat is that at the 3:28 mark, you then get to see one of the panelists, Newton Minow.) But Sidney is the first person you see, speaking from the audience for about a minute-and-a-half. And even at such a serious event, he gets a laugh. And that's a perfect combination of Sidney. You can watch the six-minute clip here.
