I HAVE wonderful friends. In this last year, one took me to Istanbul. One gave me a box of hand-crafted chocolates. Fifteen of them held two rousing, pre-posthumous wakes for me. Several wrote large checks. Two sent me a boxed set of all the Bach sacred cantatas. And one, from Texas, put a hand on my thinning shoulder, and appeared to study the ground where we were standing. He had flown in to see me.
