Answer:
A useful paradigm for analyzing Robert's behavior is Symbolic Interactionism.
Step-by-step explanation:
Symbolic Interactionism views social behavior according to language and gestures, observing how individuals socialize and interact with one another through symbols (words, gestures, facial expressions, etc.). This is how the individual begins to develop his/her self.
In this case we can analyze Robert's behavior through his various symbolic gestures, such as shaking her hand, chuckling to himself to calm her down and worrying what she thinks.
