So, I'm writing a realistic fiction piece/novel/novella/thing/whatever you want to call it, and my two main characters (male & female) have a falling-out when there around 11 years old, but are then driven back together later on. But I need to create a backstory for them when they're 11-ish so they can be driven apart so then, later on, they can be re-united and everything will be happy. Here's what I've got so far (The male character is from a first-person perspective): The way I see it, everyone will do something absolutely amazing in their lifetime, whether it being the first human to walk on Mars, or working your way up to being the supervisor of a division of cable guys. Everyone wants to be somebody. But not her. Not Kara Norzennik. She prefers to tread the Earth lightly, not disrupting anything in her path, leaving only mystery in her wake. I’ve lived next to Kara Norzennik for the last seven years, and through those seven years, I’ve come to find out that she is the most fantastic human being to walk the planet. Ever since the fourth grade, I’ve been hopelessly in love with her. Kara is one of the “popular kids.” She’s always hanging around with her boyfriend, Austin Smith, giggling away at whatever the popular kids are talking about that day. Kara and I used to be really great friends. But then there was an Incident. It happened on July 24, 2010. We were riding our little 11-year-old bikes to the playground to play whatever game it was that day. Tag, Man on Ground, Hop-Scotch, Four-Square, it didn’t end up mattering after the Incident.
