Answer:
expectancy violations
Step-by-step explanation:
The theory of expectation violations is a theory widely used in social and psychological conversations. It refers to situations where a person's expectation of someone or something is violated, as happened with Stephanie and her friend. Stephanie was taught that talking to strangers is wrong, so she had an expectation that her best friend wouldn't talk to strangers, but when her friend asks a stranger for information, Stephanie is a little disappointed because her expectation has been violated.
