just for the record,

I am motherfucking 5'4" and 107 pounds. You are approximately 6'1" and 145 pounds. So when you shove me sideways, and I literally go flying (left the ground by a few inches) into a wall of lockers, it hurts. Like an Oedipus.
Okay.
You were singing some stupid song, totally out of tune by the way, and I start laughing because your voice is so bad and you are so tone deaf that it's really hilarious. And then you get mad, or some shit, because I started laughing, and decide to shove me sideways.
We're walking in the N-wing hallway.
There are lockers all around us.
You decide to shove me left, since I'm walking on your left side.
I go into lockers.
Side first.
A lock on a locker (you know, those big shiny CHUNKS OF METAL, YEAH?) hits me well you could say that I hit it but that's beside the point smack on the upper arm.
And now I have a bruise.
On my tanned, marks-never-show-up arm.
It is about the size of a quarter.
It is red around the edges.
It hurts.
I have told you many, many, many, MANY times that I do not like it when you push OR shove OR strangle OR touch OR hurt OR grab OR shake OR poke me.
No.
"Do not like" is not strong enough.
I HATE IT. 
So I would appreciate it if you would stop.
