What is the theme of "Where Are You Going, Where Have You Been"?
One other theme that could be addressed is just what, exactly, is Arnold Friend?
There are clues sprinkled throughout the story that suggest that not only is he not a Friend, he may not even be human. Pay attention to his shoes/boots. Pay attention to the numbers on his car. And, when all is said and done, what exactly happens to Connie?
OK, I won't leave you in suspense; there's every indication that Arnold ("An old fiend") is the devil.
