In "The Fly," Mr. Woodifield is a former City clerk, meaning that he worked in some administrative capacity for a business in the financial district of London. At the time the story takes place, he has had to retire after suffering a stroke and clearly misses his former occupation. Most of the time, he stays at home with his wife and daughters, but on Tuesdays, he goes up to London to visit his former coworkers.
Woodifield does eventually leave the boss's office, but he is reluctant to do so because his conversations with old friends on his weekly visits to the city are now the highlight of his life. It is revealed that he is a younger man than the boss, meaning that he probably had not expected to retire for several more years, and what he says about his life at home makes it clear that he is bored there.
When the boss offers him whisky, he remarks that he is not allowed to drink at home and looks as though he is going to cry. The impression he creates is that he is lonely at home, despite the presence of his wife and daughters, and wants to linger as long as possible with his old friends at the office.
