The basic difference between Stranger and Neighbor exposition is:
A. stranger exposition should be avoided in favor of neighbor exposition.
B. stranger exposition refers to information shared between people who do not know each other, whereas neighbor exposition refers to information shared between people who do know each other
C. stranger exposition is awkward and neighbor exposition is elegant. Sorry, your response is incorrect.
D. stranger exposition happens in Act One, and neighbor exposition happens in Act Two.
Neither stranger exposition nor neighbor exposition is inherently better or worse. One is the way strangers talk to each other, the other is the way neighbors talk to each other. The one cardinal sin is to put stranger exposition into the mouth's of neighbors, such as having a character answer the phone saying 'Hello, Father, this is your eldest daughter Rebecca.' In this exaggerated form, it is obvious and laughable, but subtler versions can be equally awkward.
