Answer:
In the Outsiders, the differences between the two brothers become evident in the first chapter. Ponyboy, being a teenager, disapproves of his brother Darry controlling him. He finds Derry's efforts unnecessary and desperately wants more freedom. Darry, on the other hand, wants to look after him and acts as a parent-figure. He forbids Ponyboy to go out at night all alone. He is convinced that him protecting his brother is the only way to avoid the intervention of social services.
