Developing My Character

If I'm going to be shifting the focus from the smartphone to the owner of the smartphone, I need to consider who she is.

My character's name is Allison Pierce and she is a 17-year-old high school junior. Her father was born and raised in California and is of English decent, hence the surname Pierce. Her mother was born in Venezuela and at the age of 10, her family moved to Florida in pursuit of a better life. Her parents met in South Florida while attending college. They are not a religious family, however her mother is always insisting they go to church. Some of Allison's fears include spiders and swimming. When she was young she fell into the pool and almost drowned, since the incident she has refused to step foot in a body of water. She has absolutely no idea what she wants to study in college, nor what career she wants to pursue. She is an average student and always does the bare minimum. Her favorite class is Anatomy, where they are always doing dissections and cool labs. Some of her positive personality traits are that she's kind, generous, and is always willing to help someone.
Some of her negative personality traits are that she isn't observant, she's lazy, and she believes everything she hears--no matter how ridiculous the information sounds. A defining moment in her life will be the car accident she causes and kills a middle-aged man because she was texting and driving. This moment will lead her to get off her phone and start paying more attention to the world around her.
