book seller or book trader

"Every word written from the heart holds a Mystery. The reader reveals it by building a whole from the sentences recognized by the consciousness. A book is a Family of mysteries. Booksellers are grandparents who love all their family members. That is why they can tell customers about the contents of the books. Booksellers who can't do this are not grandparents. They are just traders."—from the movie The Last Bookshop of the World, cited in Shelf Awareness

I'd like to think that I was a bookseller, and not just a book trader…
