Burning bridges

(1988 February 7) Yes, it is my [84th] birthday, and I have just phoned Bill because of a headache and a snow storm with howling wind I would be staying home today. He's always kind, said to let him know if I needed anything. Well, I am not that bad off. Next I phoned Mary M and told her not to come as planned and she readily agreed - storm and headache too. ... So - having burned my bridges, I have time to write to you.
