Mortals, Tobias Wolff, THE NIGHT IN QUESTION
by Patti Abbott
A young guy, trying to make time for writing, takes a job writing obits. When he posts one of a man not dead, the man comes in. The guy loses his job and the guy takes him out for a lunch as an apology. Over lunch, the reason for the mistaken obit becomes clear.
Wolff is a great short story writer as well as a great memoirist.
