What are Pandora's character traits in The Secret Diary of Adrian Mole Aged 13 3/4?

The Secret Diary of Adrian Mole Aged 13 3/4 was written by Sue Townsend. Adrian, the main character who is 13 3/4 years old, as the title states, has a best friend named Nigel. Nigel comes from a wealthy family. This fact alone irritates Adrian a little bit, but he cannot express or articulate exactly why he somewhat loathes Nigel for it.
Pandora is a new student at the school which Adrian and Nigel attend. Nigel has an affinity for her, and they begin to go out with each other. Adrian likes Pandora as well, and he experiences feelings of resentment toward Nigel that are much more intense than his feelings about his family's wealth. Adrian and Pandora do maintain a friendship at the same time that Nigel and Pandora are going out together, however.
Pandora is smart, mature, career-focused, feminist, and sophisticated. We learn about these character traits while she is dating Adrian. For instance, Pandora tells Adrian that she is not willing to risk getting pregnant for him as they explore their sexuality. Also, Pandora does not want to get married to Adrian, or anyone else for that matter, within the next couple years because she would rather focus on her career. Additionally, Pandora comes from a wealthy family, like Nigel, and she is largely a reflection of her parents's traits, such as being career-focused and sophisticated. Adrian admires these qualities, and he believes that Pandora is the one for him.
