How does manny describe himself?

I'm not sure where Manny describes himself but I can make a general comment.

Manny is an intelligent youngster. He makes good grades at school and there is talk at one point of Manny transferring to a better school. One of his teachers notes that his grades are good enough to make it in a better school. Manny doesn't focus much of his story on education, other than to note that there are many things he doesn't know. He is aware that he would learn more in another school.

Manny has some friends, and he seems easily led into awkward situations. He accepts an invitation to a party without understanding that he isn't really welcome. He joins a group that follows a young boy's claims to be a good boxer and they are all hurt when their boxer doesn't win. He is interested in girls but is extremely shy. He is maturing quickly at this age, beginning to understand what's really important and what only seems important. He is also devoted to his family though he fully sees their faults and short-comings. As the story comes to an end, Manny understands that his two sisters are the most important people in his life and that he should pay more attention to caring for them.
