What did William Faulkner do after returning from Canada in 1918?

After returning home from his training with the Royal Air Force in Canada following the World War I armistice, William Faulkner enrolled in a few university courses and contributed poems and drawings to campus newspapers. During this period, he also adopted a self-dramatizing persona as a poet who had experienced wartime service.1

In the fall of 1921, he spent three months working in a New York bookstore before returning to Oxford, where he managed the university post office with notable negligence until he was eventually forced to resign.1
