Every story is different, but each one takes you to a different world, or an alternative view of one we are in (and perhaps wish we weren't). Some are funny, some sad and many are both. Some are so short they are more like prose poems. Great for dipping into and getting a taste of Kafka before (and during and after) tackling his larger works.
