Julia Wolf's song Captions is about a person who's constantly seeking validation and attention from others, especially from the narrator. The narrator did favors for this person without asking for anything in return, but when the tables turned, this person turned on them. Despite their actions, this person still wants to be close to the narrator and even asks for a session, but the narrator refuses. The lyrics suggest that this person has a bad habit of running back to the narrator after seeking validation elsewhere and using the narrator's lyrics as their captions on social media. The narrator advises this person to put time and effort into improving themselves instead of constantly seeking validation from others. Overall, Captions is a cautionary tale about seeking validation and attention from others and the importance of taking responsibility for one's own growth and success.
