A small laugh, quiet though appreciative, escaped Lisa at the end of the girl's statement.
"I feel as though every new search for a book will be unsuccessful," she mused as her fingers ran over the book bindings, her eyes following her hand. "Somehow I just think that no other book could satisfy me as much as the last one."
Lisa had a great appreciation for people that she felt she had no previous ties to. There was a comfortable sense in the fact that with no history, there was no actions to live up to. Lisa needn't act distant or over friendly due to whatever the girl's affiliations were during their tenure at Hogwarts. Expectations weren't impossible to overcome, just seemingly tedious. While, however, meeting a stranger, Lisa felt at ease. Nonetheless, a stranger at a bookstore.
"However," she continued as she pulled a book down from amongst the others, "I never seem to learn. I can never be disappointed with a book -- each one is put together with such care. And pride. I can't imagine undertaking the task of writing any sort of book. Putting everything you believe in into words ..." Her own words drifted off as she realized she was rambling -- a bad habit she had when encountering someone she didn't know.
"Duadem, though, has some interesting theories if Development is your subject of the moment," Lisa grinned to the girl and held out the book she was holding, offering it.
