You are an emotion inside of a teenager's head, Kailey, you can choose what emotion you are (except for the few that speak here)

Joy "Kailey got accepted into the cheer team!!" She squeals in excitement

Anxiety "Really? How do we know we'll fit in?" Anxious chuckle

Bluntness "We don't" He takes a sip from his coffee

Sarcasm "Gee, thanks for that obvious info" she says, adjusting her glasses and crossing her arms. (Choose an emotion & gender)
