It All Started With A Flip Phone

It was -her- flip phone. The exact same model, year, company. But.. she pulled her slightly battered flip phone out of her back pocket and held it in her left hand. They were nearly identical. She flipped open the one that belonged to the the mysterious stranger, and stared down in growing horror.
This is the story of Delia and a very eventful year she had. It gets pretty creepy, but awesome. Please stick with me, this is going to be an amazing story.
