There's no real meaning to this beginning. Each part talks about a character, one of the Mary Sue's/Gary Stu's.
Disclaimer: I don't own anything, but my Mary's and Gary's.
This is a story. You see the name? This is a story about three people.
She's perfect.
From her fashionable clothes, to her pedicure toes. She'd never show weakness, and chances are she wouldn't talk to you.
~Someone might see~
But see, she's just like any popular, cold person. Is she really perfect? Or average?
He couldn't be perfect, because to be perfect you have to follow rules. He doesn't follow rules unless it helps him. It's much more exciting to break the rules, even the ones too small to be noticed when broken.
He likes the rush of adrenaline. You think that's weird? At least he's not jumping off of bridges. Or perhaps his "breaking rules" attitude, breaking such small rules and only disrupting a few people in class compared to the whole class would make him look boring. Or perfect.
Uhg. He really isn't a bad guy, if you live with him, share blood with him, he'd be a friendly brother. Help you solve questions and know just what Sci Fi books to read. But don't even bother talking to him if you aren't related to him. Chances are he'll just agree with whatever you say to get away as soon as possible.
~Sigh, his shyness~
See, you wouldn't notice him. He doesn't make a scene, he doesn't have anything absolutely strange about him, really, that you can see.
~Isn't that the very thing that makes him perfect?~
They aren't people you'd take much notice on, reader, they are just Mary Sue's and Gary Stu's in their own way.
It's the WITCH that you should take notice of, if you're looking for an interesting character.
But then again, what writer wants to write Mary Sue's and Gary Stu's? They *I* wouldn't get many readers.
Perhaps this means something.
Perhaps this means that this Mary Sue and Gary Stu's aren't named Mary and Gary, on the inside.
~On The Inside. That's How it Always Goes, Doesn't it?~
Or Perhaps, for once, This Story Doesn't Have a Writer Swearing Their OH SO AMAZING OC's aren't Ms. Sue and Mr. Gary,
But instead a story about people who didn't have enough life experience to be anything but average. Average in a world of nothing but strange-ness, making them seem perfect. Nothing bad about them really, see.
But then again, doesn't the Title say there's also a Witch?
Ah, yes, amidst the Perfect-yetohsoaverage-Characters, one who's anything but average.
Now there's only one question. Are we sure it isn't Her who is the Mary Sue?
Like I said.
Take notice of the WITCH.
She might just surprise you.
Because one day, Mary Sue's and Gary Stu's will prove themselves worthy to rule the world. And they just might not annoy you all that much.
