What are some character traits of Mr. Martin and Mrs. Barrows in James Thurber's "The Catbird Seat"?

The two main characters of James Thurber's "The Catbird
Seat" are nearly polar opposites, a difference that eventually plays an important part
in the climactic ending of the story. Erwin Martin is small and quiet, a "drab, ordinary
little man," while Ulgine Barrows is large and loud, with a commanding presence. Martin
doesn't smoke or drink; he prefers milk. Mrs. Barrows smokes Luckies and drinks
scotch-and-soda. Martin has few friends and has worked with the company for 22 years.
Mrs. Barrows quickly made friends with the president of the firm, Mr. Fitweiler, and
became his "special advisor"; she has forced many changes during her eighteen months on
the job--change being something that Martin detests. Mrs. Barrows is a big sports
fan--Martin is not--and she delights in repeating various sports terms made popular by
the Brooklyn Dodgers announcer, Red Barber. Most importantly, Martin is a man who lives
by an orderly lifestyle of routine--something that is so unchanging that it becomes the
defining characteristic of the individual, and the trait that leads to Mrs. Barrows'
undoing.
