A major theme in chapter 16 was not to be too quick to judge someone. Jonathan explains how almost every time he thought he knew one of the children, they would say or do something to make his opinions change. In chapter 16, Benjamin is an example of this. Jonathan thought he was just a troubled and superficial kid who made fun of others mistakes. Benjamin was held back in the 4th grade, and more than likely was going to be held back again. But when Jonathan was with Benjamin alone, he realized he jumped to a conclusion about the boy too quickly. Jonathan doesn't really explain what his new opinion of Benjamin is, just that his first impression is now irrelevant.
A quote from this chapter that stuck out to me was from page 271, "...the largest numbers go to Morris high, a school I visit every couple years and where, each time I do, I find myself peculiarly surprised when I am told the statistics are no better than they were the last time I was there. Approximately 1,900 boys and girls are still enrolled each year at Morris High, about 1,200 of them in the ninth-grade class alone; but there are seldom more than 65-out of 1,900!- who get to the twelfth grade and receive diplomas." This quote just blew my mind with the statistics that it gave. That just really put things into perspective for me since I had about 375 people in my graduating class.
