This is typical and always warms your heart. I once had a new young employee who disappeared from work after checking out lots of books. I tried, but couldn’t find her- worried about her for years.
A few years ago I ran into her and she told me that she took her young child and ran from an abusive situation. She still had the books. They helped her stay centered and she read them to her little one. I told her I was very happy that they gave her comfort and told her to just keep them.
