Who am i?

Tattoo?

"What the hell did you do that for?!" i said. "She was the one that ran". "Just tell me what you want. " "I came to talk to you about something serious. What the hell did mom tell you about getting a tattoo?" I was shocked at the question cuz i never disobeyed my mom. I saw him point at my chest. I looked down and saw them there. A black tattoo that started at my chest and spread so it looked like a cross. It looked just like my necklace. "When did that get there?!" I was just as surprised. But i remembered that guy had the knife and it was pretty close to my chest. What the hell is going on?.. I went to school the next day and was walking to my class when i saw Skylar. She was talking to some guy and when i waved she smiled and i could see her cute little dimples. But the guy looked at me too and he looked like he was ready to kill. I walked up to them and acted like i didnt notice him. "Hey Sky we better get to class or we're gonna be late." The guy just sneered. "Shes my girl friend and shes coming with me!" He grabbed her wrist and i dont know what came over me. I grabbed him by the collar and slammed him to the lockers. I felt a tingle on my chest but shrug it off. "She might be your girl friend but she is not your god damn property." He was pretty weak even though he looked like a jock. Everyone looked at us with a look that said a fight was about to happen. "I'm not his girlfriend, i just broke up with him." "You little bitch!!" he said with a loud ass voice. I snapped and knead him in the chest and hit the side of his face with my elbow. "Go on Sky." i said with a surprisingly calm voice. "I dumped him cuz i caught him cheating on me and i finally said something." I looked at him with a deadly stair that said I've heard enough. He was just looking at me in shock with tears in his eyes cuz i hit him. "Touch her again and i will kick your ass so bad that you'll be praying to God to save you." I left with Skyler to homeroom and i noticed that through a gap in my shirt that the tattoo was glowing and it was a dark navy blue. "What the fuck?.." Skyler grabbed my arm and pulled me so she could kiss my cheek. "Thank you for helping me." then out of nowhere she slapped me. "Thats for starting a fight." I couldnt make heads or tales of it but i knew she was different than all the other girls and sluts.
