Invent three characters, at least one of whom is a teenager. Make a character sketch of each. Create character's names, ages, and most important character traits here.
Use these questions as you develop your character sketch:
What details could I use to physically describe this person to a friend?
What is unique about this person's behavior?
How does this person talk?
Does he speak with an accent?
Is he well educated?
What experiences or words used by this character give us a clearer picture of who he is?
