Answer and Explanation:
Direct characterization occurs when the narrator directly says what a character is like.
For example: Professor Shlemiel calls himself "forgetful" and says he's always blundering and losing things.
Indirect characterization is when the narrator shows indirectly some characteristics about someone in the story. It may be through the character's actions, opinions, or things other characters say.
For example: Professor Shlemiel's wife, long familiar with his behavior, warns him, "Now, don't forget your address."
