Final answer:
Otto's statement about the jeans being awesome reflects the role of social norms in teenage social development, where clothing can contribute to feeling included and happier.
Step-by-step explanation:
When 13-year-old Otto tells his friend that their jeans are "way awesome," it reflects the importance of social norms among teens and preteens. During this stage in life, fitting in and being acknowledged positively by peers is often crucial to their social development. Clothing choices often serve as a means of social acceptance and can influence a teenager's happiness and self-esteem.
It should be noted that fitting in with certain clothing styles doesn't guarantee popularity, but it can make an individual feel happier as they perceive themselves as part of the group. This desire to fit in is a common aspect of lifespan development, especially during the transition from childhood to adolescence.
As young people grow, the influence of social norms may evolve, but during middle school years, adherence to popular trends is a significant aspect of social interaction.
