Tom has always liked Lucy, but Lucy has always thought Tom was annoying and unattractive. One day, Lucy comes home to find an eviction notice on her door. Apparently, her roommate has been spending the rent money that Lucy was giving her on other things. Lucy only has 24 hours to get all her stuff over to her mom’s house, and Lucy doesn’t even have a car. But Tom has a truck. So Lucy calls up Tom and asks him how he’s doing. She tells him that she’s always thought he was funny, and that they should hang out sometime. Tom thinks that Lucy has finally come around and is beginning to like him. He also thinks that his jokes are funny because she is laughing at everything he says. Which type of irony is used? And why?
