Several Christmas cards were late in arriving this years, cards which normally arrive on time & have been doing so for years and years.  Of course these three cards gave us some concern.  Two were from women I have known almost my entire life.  Those, to my relief, arrived yesterday.  The third one didn’t.  Keith did an internet search this morning & sadly found this person in the L.A. Times obituaries from November.  Don was Keith’s boss at Caltech, the person who gave him his first job after he graduated.  He was a wonderful person & we will miss him.  We didn’t see him often, still it is very sad to know we will never see him again.
