Shattering Illusions

Write a dialogue that dramatically uncovers a bitter truth, shattering a character’s illusions.

In many drama stories, a pivotal moment is when a character’s preconceived notions or illusions are broken, often in a striking manner. This prompt allows you to construct a dialogue where a character comes face to face with an unpleasant truth. What is the character’s initial reaction and how does this change over the course of the conversation? What choice of wordings can amplify the shock and consequent realization?
