She furrowed her eyebrows together and looked down for a moment at the girl's question, trying to think of a few wizarding occupations she could name. However, Luna spouted out a few instead. Jane really didn't know of many jobs in the wizarding world. The only ones she had done any research on involved magical creatures, so everything that Luna had just relayed was news to her as well.
As Luna talked, Jane looked down into her lap, twirling her thumbs about each other. There was really nothing she could add that would be helpful.
With the addition of another person to their table, Jane was a bit concerned about making too much noise in the library. Her friends at school had always accused her of being too much of a stickler for the rules though, so Jane kept her lips sealed on the issue, not wanting to seem like a downer.
After Luna seemed to have finished speaking, Jane decided the best way to start a possible friendship was with a simple introduction. Whether or not the girl was looking for a friend, she did still need to know names. Jane smiled kindly at the girl and extended a hand out. "My name is Jane Greenway. It's nice to meet you."
