Read this line from The Outsiders by S. E. Hinton.It drives my brother Darry nuts when I do stuff like that, 'cause I'm supposed to be smart.

The line points to tension between Ponyboy and his brother Darry: Darry gets upset when Ponyboy does things he considers foolish. That makes it a struggle between an individual and another person. The mention of being “supposed to be smart” explains what causes the tension, rather than showing a conflict with the environment or a group.
