How to talk in Robot

Day 1 of 365

Walking down the road with my backpack going to any place that might catch my interest. Dangerous right? Not quite, I'm a Beta Human, we are faster, stronger, most of us are smarter, more appealing to the human eye. One thing we lack in all this, human emotion. Gotta have a fault right? So we spend years training to be perfect and if we make it, we get to go out and see if its possible to live normally in the human society.
My name is no longer 3281997, it's Sam Kelly , I am a 17 year old female teenager. I'm the daughter of Shelby and Steven Kelly who allowed me to be emancipated and go as I please. That's my story the basics, lying isn't a problem, we are trained to be perfect liars which in our society was normal. 
"Hey!" A shout makes its way to my hyper sensitive ears, I don't stop. The loud buzzing noise gets louder, I prepare for a fight. A scooter type thing pulls up and slows down by me.
"Are you okay?" The person asks, face covered by a helmet. Teenage boy from the voice and body, I stop and glance around, maybe I could get a ride to the closetest town? 
"Hi, well I actually am in a pickle. I was trying to help a person out with their car, and my friend went to go to the closest town and hasn't came back so I'm just praying I'm headed in the correct direction."  I smiled at the boy, knowing he would believe my story and hopefully help me out.

"I can give you a ride. It's like 20 minutes unless you're walking." I didn't hear any spikes in the boys heartbeat so I smiled and got on his little scooter thing, the whole way planning the next few months out and how it was all gonna work out in...Laden, population 3,000 people plus me; 3,001.
We pull up to the diner, I get off the boys scooter, thank him and head off in the other direction.
"Wait!" The young male calls after me, I stop and wait as I can hear him running after me.
"Where are you going to go? There isnt a whole lot to this town." The boy asks me, I look him over, he is a little taller than the average male for his age. Brown blonde hair, green eyes, nice tan skin, hes attractive, why would he be interested in helping me, a stranger unless he wished for something in return.
"Why does it matter to you?" My tone was harsh and suspicion range clear in it.
"You shouldn't go wondering by yourself, its a nice town but every town has darkness in it. Why dont you come and have some food  and see if anyone has seen your friend." He motions toward the diner, I have to go for the sake of my "friend". I sigh and follow him, he seems to want to say something but doesn't know how, I perfer silence anyway.
He opens the door for me for  enter, I thank him and step inside to be greeted by lots of human noise. Yelling, talking, music, clanking it took me a moment to adjust to the noise. I follow the boy to a table and sit down across from him, remaning silent.
"Y'all ready to order?" A youngish woman in a uniform asks, I look at the boy he looks at me, crap.
"May I see a menu please?" She nods and comes back with one saying she would give me a few mintues. I decide to get a hamburger, fries and a chocolate milk shake. She returns, looking st the boy, trying to get his attention but fails, I wish I could feel sorry for the poor girl. She takes our orders and my menu, I look out the window to see a group of teens yelling at a young girl. I watch one guy get closer to her, I stand up and walk out the door, the boy coming after me.
"Dont you know that no one wants you here." One of the punks sneers at the girl.

"Why dont you shut your fucking mouth you little punk." I call out to him from behind him. He whips around to see me standing there in my all black outfit and combat boots, this boy wanted to fight I'd give him a fight he would easily loose.

"Who the hell are you bitch?" The punk yells, acting tough, but oh can I smell his fear.

"I'm the bitch who will hand you your ass if you dont leave that girl alone." I take a step forward, he doesn't move, the boy has went over to the girl and pulled her away from any danger.

"Right, you hand me my ass. You're nothing but a emo girl who thinks she's all tough and badass, well honey I'll make both of you scream my name." He winks and I keep my face blank, is this little punk flirting with me? He seems off put that I am not impressed, I take another step forward, he copies me. Challenge accepted bitch. He looks at me, thinking his weight will give all the advantage he needs to show me. I wait, he comes and tries to push me, I duck and pull his arm back behind his back, kick at the joints of his knee and back of his leg, he falls to his knees.
"Now what were you saying little bitch?" I sneered at him, I heard people laughing and clapping. He was pissed, I saw him motion to one of his guys to come at me. I saw him pull out a knife, I hit punk number ones pressure point making him fall asleep, the other one charges at me, I move quickly and punch him in the nose, a satisifying crunch came as my first connected with this nose.
"You broke my nose, prepare to die bitch!!" I rolled my eyes, and ducked as he came at me with the knife. I flipped backward, swipped his feet from out under him, knocking him on his back. I take the knife outta his hand and put it at his male genitals, looking at him daring him to say a single word out of place .
"Please dont." The big tough man with a knife was crying, begging me to not make him a true bitch. I lean over and let him see my face, how I have no pity for the sorry excuse of a human being.
"Leave, never return. If you ever hurt another person or do another wrong deed, I will find you and finish what I started bitch." With that I threw the knife in the dumpster and walked away from the scene that had gathered around us. So much for staying low key...
