Seth and Carson grew up together. They met in preschool and hated each other since Seth was a trouble maker and Carson was a sweet kind girl.
In kindergarten their mothers became friends forcing them to be friends. They started getting along. They acted like brother and sister while beating each other up or racing around the parking lot. As they grew up they were teased about being best friends. They didn't care but even their mothers said they were going to get married some day. After 3rd grade Carson and her family moved away to Boston MA.
Seth saw Carson only a few times a year. They both had changed in many ways. They were still very tall but Carson became a tomboy. She became more athletic and a huge boston sports fan. Seth became very self conscious and tried his best to fit in but still didn't.
