Fernando works as a teller in a bank. He observes that fellow workers at his bank have a congenial and easy-going interpersonal rapport with one another. For instance, it is common for co-workers to use first names when addressing one another — except for the bank manager whom they all address as Mr. Caspian. At the same time, there are boundaries that govern how deeply staff members may share personal information. Most of the social interaction at work is confined to small talk, discussing news and sharing superficial information about past history and a little bit of information about the family background of each person, but certainly no significant depth of disclosure about personal information. Indeed, when one former employee became too personal with co-workers, she was actually asked to moderate her disclosures. Mr. Caspian was concerned that her more personal self-disclosures might cause some members of the staff to feel uncomfortable. In light of the way our textbook examines contexts of interpersonal communication, which of the following seem to describe how people interact interpersonally at Fernando's workplace?
A) Self-disclosure is guided by regulative rules.
B) There are different levels of formality that govern interactions among bank employees.
C) Co-workers do not relate to one another on the basis of psychological knowledge.
D) all of the above
