I knew a girl in high school by the name of Shannon. We weren't necessarily friends, but knew of one another's existence (at least I knew who she was, can't speak for her). And I had a boss for several years while working in Beverly Hills, also named Shannon. But this tradition (to be discussed below) all started up long before I met Beverly Hills Shannon.
Beginning with my very first screenplay, a zombie spec called, Sid's Apple, I've tried to have a character in each of my pieces, with the name "Shannon". It didn't start out as a "thing", it just naturally progressed.
You see -- in Sid's Apple, Shannon was a nosy neighbor of my lead character, Sid. Thing is, she was also a zombie. So, an undead nosy neighbor.
And my second script (another zombie tale), Me & Simon Baker -- well, I needed a neighbor of my main character to turn into a zombie, and I thought, "Wouldn't that be a hoot? To have this character be basically the same person? Aren't I clever?"
Those original instances were at least organic, and now it's sorta stuck with me and become a tradition.
Shannon -- never again the same character as those original zombie neighbors -- but she (haven't had a dude yet) still shows up, in name only. I just thought it'd be a fun exercise to call out her many memorable appearances.
Sid's Apple: An undead and annoying neighbor.
Me & Simon Baker: A soon to be undead and annoying neighbor.
A. Family Portrait: A precocious 8-year old girl.
Silver Spoon: The nerdy and heroic girlfriend of almost-hero and super-fan Roach.
Furnish: An assistant manager in an upscale, Beverly Hills furniture store.
Spider Eaters: An Australian cattle dog.
The Costume People: A no-nonsense theatre stage manager.
Mom Died: A funeral home director.
Trip: A waitress at a down-home burger place.
Also, in one of my first novels (currently in the works), a secondary character was christened "Shannon".
Thought I'd share. Do you all have any habits or traditions you follow in your writing?
And I'll just close with this: LONG LIVE SHANNON!
