Let's just structure the excerpt a bit better. I was able to find it online:
I know I’m not an ordinary ten-year-old kid. I mean, sure, I do ordinary things. I eat ice cream. I ride my bike. I play ball. I have an XBox. Stuff like that makes me ordinary. I guess. And I feel ordinary. Inside. But I know ordinary kids don’t make other ordinary kids run away screaming in playgrounds. I know ordinary kids don’t get stared at wherever they go.
Answer:
The excerpt is in the first-person perspective.
Explanation:
A first-person narrator uses first-person pronouns such as "I" and "me" and gives us his / her own perspective on things. The reader, therefore, only receives the information known and offered by the narrator. That means everything we get to know is biased, since it comes permeated by the narrator's feelings and opinions. Notice that the excerpt we are analyzing here uses first-person pronouns. This narrator is describing him/herself. We get a glimpse of the way he/she feels - "And I feel ordinary. Inside" - and thinks.
