There came an awful day when I picked up the phone and knew at once, as one does with some old friends even before they speak, that it was Edward. He sounded as if he were calling from the bottom of a well. I still thank my stars that I didn't say what I nearly said, because the good professor's phone pals were used to cheering or teasing him out of bouts of pessimism and insecurity when he would sometimes say ridiculous things like: 'I hope you don't mind being disturbed by some mere wog and upstart.' The remedy for this was not to indulge it but to reply with bracing and satirical stuff which would soon get the gurgling laugh back into his throat. But I'm glad I didn't say, 'What, Edward, splashing about again in the waters of self-pity?' because this time he was calling to tell me that he had contracted a rare strain of leukemia. Not at all untypically, he used the occasion to remind me that it was very important always to make and keep regular appointments with one’s physician.
