You're walking down the street one evening, and you see your ex-girlfriend walking towards you. Your heart sinks as memories of the past flood back into your mind, but you're determined not to let it get the best of you. As you catch sight of each other, she starts to smile, and you quickly turn away. You hear her calling out your name, but you keep walking as you don't want to get into a conversation. As you continue to walk past each other, she turns suddenly and catches your arm.
