Manny's friend experienced encoding failure when he could not recall their conversation because he didn't pay attention to their talk.

Explanation:

First of all, this is a very big phenomenon that could be triggered by many factors. Disperse attention, encoding failure, proactive interference or passive listening. But here is the thing that makes it fall into encoding failure. He couldn't recall anything at all. So, proactive interference and all of the phenomenons related to picking only something from the talk are discarded.

This can be generated by trauma or substance abuse.
