Percy should try to make himself more enjoyable to hang out with. The evidence is that Percy was annoying Annabeth with questions why their parents don’t go along (in Chapter 10). In the video about how to build trust and relationships, they mentioned that asking questions that people will enjoy answering will encourage them to talk about themselves. Plus, many people find it uncomfortable to talk about their personal lives. If Percy wants to be friends with Annabeth, he really should try to ask better questions.
