Though Yahaira seems to find Dre’s love of Nina Simone somewhat ridiculous, it’s worth noting that listening to music seems to give Dre a healthy outlet to deal with her difficult emotions. Yahaira, on the other hand,
wants to get upset and break things, though she never actually does this. This suggests that Yahaira habitually keeps her feelings inside and hasn’t yet found an outlet for her emotions when things get rough. She can coexist with Dre and borrow Dre’s outlet in this passage, but Yahaira doesn’t seem to feel much better with Dre’s earbud.
