Adie's P.O.V
When school was over I walked home still holding onto the picture,tickets,and their phone numbers. This all has to mean something. Maybe their trying to get me out of this hellhole and give me a better life. I dont know. But I cant wait until I go to California. As I walked down the street towards my house I saw a black car in the driveway."What the hell?" I wispered to myself. When I walked to the front door I saw a note on it. "Adie,Theres a problem with the door so come around the back. Love, Mom" I know the door worked fine when I left this morning. Whatever I go around the back. When I got to the back door I saw someone sitting on the patio chair. I could only see a siloette of the person. But I could tell that he was about my height. I should have known who it was but my brain was so messed up between thinking about that picture and the tickets. "Hello?" I said walking toward the person. "Hey Happy Birthday!" Wait I knew that voice. It sounded so familar. "Tre?" I said. "Damnit! How did you know it was me?" "I know your voice and I can see you fauxhawk in the shadow. Why are you here" Im your birthday present." He said giving me that evil grin and raising his eyebrows "Hey where is everyone else?" I asked "Oh your mom is at the store and Im the only one here." "Sure Tre I believe you." Of course I didnt. Something was deffently going on here. "Lets go inside Im freezing my balls off." "Tre you only have one." I started laughing and he picked me up and put me over his shoulder, When we got inside he put me down and everything looked pretty normal. The lights were on probably because my mom knew that Tre was still here. "I wanna go change and put my stuff down." "Okay" Tre said as he looked around my living room like he was in a mueseum. I walked to my room and opened the door. "AHHH!" I screamed because Mike and Billie where just standing in there staring at my posters of them. "Wow. I look good in that picture." Billie said. "Adie!" Mike said with excitment. He grabbed me and spun me around while hugging me. "Hey its my turn." Billie said. We hugged for what seemed like forever,
