Sharon avoids talking on the phone because ending a conversation is so awkward. how would dramaturgical theory explain why it is more difficult to end a conversation (closing) when on the phone than in person?

Dramaturgical theory states that the elements of human interactions are contingent upon the time, place, and audience. So for this question, it is quite impossible for people to see our closing gestures, many of which are nonverbal language because we are using the phone.
