The three sentences that are used to develop the narrator’s personality are: "I remember that song, and it always makes me feel a little sad to hear it," I admitted to Rosie. I knelt down next to the woman's dog and said, "He's a beautiful dog. What's his name?" "You just say that because you're jealous," I said to Marty as I put my license back in my wallet.
What these three statements have in common is the use of adjectives and verbs to describe the mood or the feelings of the narrator. Examples of emotions can be found in the tree statements, such as “makes me feel a little sad” “beautiful dog”, “you’re jealous”. The other two statements are informative.
