 Real world example
 
-> We are persisting rainbowfish objects to file and later on they need to be restored. What makes it problematic is that rainbowfish data structure is versioned and evolves over time. New version of rainbowfish needs to be able to restore old versions as well.

 Use the Tolerant Reader pattern when
 
 * The communication schema can evolve and change and yet the receiving side should not break
