In what ways is Jim's attitude like the other boys of the town?

Black Hawk is a nice, clean little town with a river that reminds Jim of the country. Soon the Burden family feels like town people, and Jim learns boyish ways at school. 

Suddenly put down among boys of my own age, I found I had a great deal to learn. Before the spring term of school was over, I could fight, play 'keeps,' tease the little girls, and use forbidden words as well as any boy in my class. I was restrained from utter savagery only by the fact that Mrs. Harling, our nearest neighbour, kept an eye on me, and if my behaviour went beyond certain bounds I was not permitted to come into her yard or to play with her jolly children.
