A personal narrative tells the story of an event from a first hand perspective of the person who is telling the narrative.
This narrative will therefore take a point of view that is that of the narrator. The first paragraph being the introduction, must therefore at least show this point of view so that the reader might know where the narrator observed the event from.
It is a persuasion. As his use of tone suggests that he wants to convince his target audience to think about his opinions by stating facts which are true and cause us to reflect and do the right thing.
