What is a conversation between characters called?
A conversation between characters is called a 'dialogue.'
Give an example of how a conversation between the person answering the phone at a doctors office and the patient who called could create a contract?
Technically, you just used it in a sentence right there! :) But I assume you wanted more examples: I had a conversation with a friend They are having a conversation We had a wonderful conversation The conversation was long The conversation was boring The conversation between Ana and Paul was highly flirtatious.
