Let’s say you’re in the office and you’re telling a story about someone.  First you talk about what the person did. Maybe it’s something juicy, like a secret infidelity with a prison inmate, or maybe it’s something subtle, like they moved away from home.  Then you go on to tell about something more recent, like, “Just the other day she was caught using her work phone to talk to this guy in prison.”  This is the offbeat writing technique of the first person peripheral.
