Susan, I'm touched by your story (and your telling of it). I knew Jonathan for many years, though never well. But I always thought of him as shy. Sure, he could take over a room and carry everyone happily along as many have said here. But in matters of the heart, he seemed shy and unsure of his footing. I always found that sweet, because I was otherwise so in awe of him.
I invited him to my wedding in 1982, and to my surprise he came. He peeked in the door of the church, left a bottle of single malt whisky and slipped away again. Linda saw him, but I didn't. They say that every wedding you go to is your own wedding, so I always figured that he found the whole affair too poignant. Or maybe it was just too formal or too churchy. But Susan, I'm glad to hear that you were close to him.
