Minor character

A minor character in  The Fault in Our Stars would be Hazel's dad. He's not in the story much, she usually only mentions him when he's crying which happens a lot. He's usually crying since his daughter has cancer, and is scared she's going to die or something. I think if he was more of a major role, like it would describe him more and him being with Hazel or have his view on why he was crying and what he's afraid of, I think it would be better. I would love to see his view on things and hear about him and Hazel more. It would make you feel bad for her dad more if you knew why he was crying instead of getting annoyed with it.
