this point of view shows the reader how everyone in the story is feeling which creates a proud tone.
the story gives the reader just the main character's thoughts and emotions, so the longing tone is magnified and clarified.
the first person point of view allows the reader to sense the reflective tone sylvester had when looking back on this incident.
since the story is told from multiple points of view, the tone varies depending upon each perspective.

- "a nonrestrictive clause functions as a modifier to a noun (that is an object, person or concept). these clauses can be described by the following three options: it is set off by comas, it contains a subject and a verbs and it adds nonessential information to the sentence.

for example, in "here is bill gates, who confounded microsoft software company" we can identify "who confounded microsoft software company" as a nonrestrictive clause modifying the noun bill gates. this clause can be describes as a nonrestrictive clause because it is separated by a comma, it adds nonessential information to identify who bill gates is and it must contain both a subject (who) and a verb (confounded)."
