 Why did Orison prefer to send her reports to Washington by mail?
Orison switched off her microphone at noon, marked her place in the book and took the elevator down to the ground floor. Girls from the ground-floor offices of Taft Bank chattered together, eyed Orison with the coolness due so attractive a competitor, and favored her with no gambit to enter their conversations. Orison sighed, finished her tuna salad on whole-wheat, then went back upstairs to her lonely desk and her microphone. Orison briefed her pillow on the Earmuffs, on her task of reading to a microphone, and on the generally mimsy tone of the William Howard Taft National Bank and Trust Company. Orison flung the shoe and the pillow under her bed, and resolved to write Washington for permission to make her future reports by registered mail.
 She found the “pillow talk” to be improper.
 She preferred to put everything in writing.  She found the “pillow talk” to be improper.  So the reports could be done faster.  So the reports would be more secure.
