Answer:
The bar owner and the boy are foil characters; this may foreshadow the boy’s future relationships.
Step-by-step explanation:
According to the text above, we can see that the boy and his friend are foil characters, that is, they are each other's rank. The boy seems to be very innocent about his environment, in addition to appearing to be more impatient. The friend, on the other hand, seems to be more patient and experienced about the environment in which they live. This obvious difference between them, may establish a friendship in the future (an example of foreshadowing) of the narrative, which will make the story more attractive to the reader.
