A school in Connecticut once held "a day devoted to the arts," and I was asked if I would come and talk about writing as a vocation [1]. When I arrived I found that a
second speaker has been invited - Dr. Brock (as I'll call him), a surgeon who had
recently begun to write and had sold some stories to magazines. He was going to
talk about writing as an avocation [2]. That made us a panel, and we sat down to
face a crowd of students and teachers and parents, all eager to learn the secrets of
our glamorous [3] work. [4]

Is the writer being serious or sarcastic when he uses the phrase "glamorous work"? What is he implying?
