Jim is starting to enjoy football more than he used to because it gives him the opportunity to show case his manlyness and his is becoming quite cocky about it "Jem thinks Atticus is an old man since Atticus will not play football in the church league. In fact, Atticus is not particularly old; however, he does know his physical limitations. The view of Atticus as an old man who cannot really do anything is also seen in the Ol' Tim Johnson shooting incident, as well(256). "
Jim is also starting to tell scout to grow up or to stop doing certain things. When he thinks she is being un ladylike he will tell her to grow up like with the small creature that she found and he said to put it outside and don't bother it.
