Answer:
Kellys' Introverted Temperament.
Step-by-step explanation:
Just a short but necessary explanation on what a theme means. A theme can be said to amongst many things mean the concept or the view that a writer is trying to pass out as a message to the audience or the reader. It is the subject of the piece. A theme is also how the writer understands the world or his perspective of a situation.
The theme of quietly struggling is based on Kelly's Introverted temperament.
