Despite the stress of surviving in a new city as a young adult, Eggers concentrates on cultivating a fun, lighthearted, happy environment for Toph. While Kirsten worries about getting a job, Eggers plays games with his little brother, and though this might seem immature, it’s worth bearing in mind that he’s trying to make this transition easier on Toph. As such, one might argue that he’s displaying a remarkable amount of responsibility, even if it seems like he’s just goofing around and not taking life seriously.
