Citing evidence from the text, describe what kind of friend Diana was?

Perhaps Lyddie's most important mentor is Diana Goss, who teaches her how to run the looms and to question her treatment at the factory. Diana is viewed as a radical because she fights for labor reform, yet she never forces her ideas on Lyddie. Diana, who is an orphan, thinks of the factory girls as her family and treats Lyddie as a sister.

Diana did not smile ironically or laugh as Betsy was sure to. She did not once lecture her as though she were a slow child the way Amelia often did—or offer a single explanation _ as Prudence would have felt obliged to. No, the tall girl perched on the edge of a bed and listened silently and intently until Lyddie ran out of story to tell. Lyddie was a bit breathless, never having said so many words in the space of so few minutes in her life.

Lyddie made as if to sympathize, but Diana shook it off. “I think of the mill as my family. It gives me plenty of sisters to worry about. But,” she said, “I don’t think I need to worry about you. You don’t know what it is not to work hard, do you?”

Diana was helping the new girls settle in, teaching them just as she had taught Lyddie in the spring. Lyddie herself was far too busy to help anyone else.
