Frank Gallagher is a good example of perception. Frank thinks that the world owes him something and always makes a point of it. From doing things like stealing money or drugs, because he “deserves them”. Franks perception of the world is a lot different from the everyone’s around him. Frank thinks this because he has had a difficult life and he believes that he deserves better. But through others perceptions, he has created his difficult times from the choices he has made and does not deserve anything from the world.
