You grab your phone and put your keys in your lab coat and walk down stairs from your apartment.
Saying "and" twice in a sentence without a comma. Bad.
You live in a typical apartment in the middle of an average city, with the average amount of rapes and murders.
Not helping your case that that this isn't a porno or about a serial killer lol.
You leave your apartment and walk down the street to the high school that the lecture is being held in.
They have lectures in high school? Apart from assemblies I didn't see actual lectures until college.
The high school is fairly close but due to too many nights experimenting on shit, you aren't in the best physical shape by the time you reach the high school.
What in the hell are you experimenting on that would result in you being in bad shape?
I mean you aren't fat, but you're skinny as a stick.
Why are you saying "I"? Author should have no place making comments in a story like this. Next line is fine, but then...
There are many other people in lab coats similar to yours that walk by into the high school.
Why in the hell are these people meeting at a high school? That's sketchy as hell lol.
A female catches your eye as she walks by.
Target acquired.
She has long flowing black hair all the way to her shoulders and looks down, while carrying a book.
What? You describe her, then say she looks down, while carrying a book? What does the act of looking down have to do with carrying a book? Describing her then saying she does an action flows terribly here.
Your eyes make contact and she quickly breaks her sight and walks even faster. Man you sure seem creepy.
Author commenting again, bad. At least you recognize just how creepy this scenario is lol.
Time travel is what made you quit high school to develop your own time machine, or was a it black hole generator?
What? I don't even. Why would time travel, or a black hole generator, make you quit high school? I mean high school isn't even hard.
You walk into classroom and there are many other scientists seated, many much older than you. You see the girl you saw before sitting alone in the corner.
Call me crazy, but I think a bunch of scientist who walk around in lab coats would be swarming all over the lone girl in the room :P
There's only one available seat left, and guess what, it's right next to her.
THE POWER OF PLOT COMPELS YOU!
When you do, she inches away from you, and grips the book she was holding before, tighter than ever.
Just when you thought the main character wasn't creepy, you reaffirm that he is in fact creepy.
He goes on a huge lecture about why it's invalid but Kallen seems to beat him in every single one of his arguments. Eventually the professor seems to give up and his face is blood red from the rage.
Well, if you say so...
Kallen satisfied and walks out of the room as well.
All of my what?
You have to find out more about this girl. You walk out of the room and see her leaving. You follow her out of the school, keeping out of her sight.
God damn this character is creepy, lol.
Anyway, it needs some work. Primarily you need to work on...making your character not so damn creepy, haha. Also got to work on your sentence structure.
