Nothing adds interest like an old acquaintance showing up.
Imagine standing in line t buy theater tickets when a voice from the past interrupts your thinking. You don’t recognize them at first as it’s been quite a long time since you last saw him/her. What happens? Who speaks first?
What does your character do when recognition blooms?
Your task is to write a story in which someone from the past, hopefully a long lost friend appears.
Have fun with this one.
