Then I got very lucky, again. When we first sat down Robert and his other sons weren't there; the empty chairs were next to me. I got up and went to the ladies room. When I returned I found the people who originally sat next to Richard had moved next to me. Robert sat next to Richard and across the table from me. My seat partner was the groom's stepfather, a lovely man I had met several times before. Memories abounded, but they were not unpleasant. Of course, none of us recognized each other. Time had clearly done its terrible work.
I had a chance to talk to Robert's other two sons, whom I hadn't seen since they were toddlers. One was particularly charming; I was pleased.
As for the wedding: the bride was beautiful (I think she is probably always beautiful); the ambiance was lovely; food was good; drinks abundant; music too loud; everyone had a good time.
