It uses the absurdity of the character's life to emphasize how society's expectations affect a person's behaviors. An example of this is the nun. A nun is dedicated to being married to God and does not abandon herself to the things of the world. She tries to hide what she really is, but her appearance gives it away: “She was indeed by no means undersized. . .she wore a coral trinket. . ./ a set of pearls,/ from which hung a golden brooch of the most brilliant splendor” (Chaucer 160-164). This shows how the nun did not meet the expectations set for nuns. Which is a situational irony, because one would expect her to behave the way she was taught to behave, but she still does what she wants. She believes in her religion and wants to be the best she can be, which is evident as she tries to hide her unladylike ways. Despite this, she continues to wear her precious jewelry and indulge in the foods she loves. Chaucer also shows the irony of the situation in the summoner's position. The Invoker will allow the guilty to avoid excommunication “Thus, as he pleased, the man could exercise coercion/ On any young man in the diocese./ He knew all their secrets, they did what he said” (Chaucer 681-683). This is ironic because the summoner works with the church to get rid of bad people; Yet the summoner is not only a bad person, he makes deals with them so they can stay and then blackmails them..
