- A book you loved and recommended to someone becomes their new favorite
- An author finds you twitter after you post a review of their book and ends up saying hi to your book group
- A book you bought for your library ends up getting made into a movie and checks out a bunch of times
- You recommend an entire stack of books to someone and they end up checking all of them out
- A book you bought for your library ends up winning a major award and checks out a bunch of times
…all of these make me feel warm, bookish fuzzies.
