Carlos is am introvert on the myers-briggs indicator, according to the test he is

According to the Myers- Briggs test, if the results say that a person is an introvert, it means that an individual prefers to reflect, then act, then reflect again.  It is said that introverts prefer having quiet times alone and away from activity. They direct their flow inward and toward concepts and ideas.  While extraverts are action- oriented, seek breadth and knowledge/influence, prefer more interaction and recharge their energy and recharging from spending time with people, introverts are the direct opposite from these individuals. Introverts are thought-oriented, seek depth of knowledge/ influence, prefer substantial interaction and recharge and get their energy from spending time alone.

explanation:

it's important for any number of settings.   but then i'm a retired teacher and my view may be biased.

it certainly will not weigh as a minus when applying to a college, while poor grades always work against you.

other factors are important like what you do to improve the community.  

1. this would be first person. it would be like "i walked home from school today" they are the narrator of the story and is a character as well.

2. first person because they used the word "i" in the quote.

3. i'm really not sure about this one i'm really sorry i never read it so i wouldn't know how to answer it. 

4. it would be character vs. society because everyone he meets there is always a conflict of some sort because he's stuck in his daydream.

5. it would be sadness at the loss of youth because the title itself tells us it's about age so it couldn't be about regret. and the tone just sounds sad, not angry. 

i hope this !
