How are Ponyboy and Darry similar and different?

Ponyboy and Darry have many subtle similarities and differences between them. First, they are brothers, and they both have the same experience of losing their parents, though they sometimes deal with it differently. Still, the experience has changed them both. They both identify as greasers. The two brothers look very different physically, however, as Darry has a muscular physique, dark brown hair, and eyes like ice. Ponyboy, on the other hand, is smaller and slight, with light brown hair and greenish eyes.
In temperament and personality, they are very different as well. Darry sometimes becomes angry with Ponyboy when he feels that Ponyboy isn't taking everything seriously, because Darry is much older than he is and tries to be as “grown up” as possible. He attempts to care for Ponyboy and keep him out of trouble, which doesn’t always work, because Ponyboy has a mind of his own; in fact, trouble seems to find both of them. Ponyboy spends a lot of time dreaming and pursuing more creative endeavors, and Darry sometimes gets annoyed with him because of that.
Since Darry had to grow up too soon in order to take care of Ponyboy and keep him out of foster care, he doesn’t have the same opportunities that Ponyboy will in life. Darry is smart and received a scholarship based on his performance in sports, but he had to give it up. Ponyboy is intelligent and has the brains to make something of himself in the future, but he doesn’t always want the same things as Darry.
Darry has been hardened by the responsibilities that fell on him, while Ponyboy has been softened by losing his parents. Still, both of the boys are very proud of each other; they share that sentiment in common.
