Why does he like Me?

Hi my name is, Alli (like alley but with am "I" instead of "EY") Perez. I am 17 and i have 4 brothers 2 sisters 2 dogs, and I live with my dad and grandma. You see, my mom died giving birth to my little sister 2 years ago. I have a best friend named, Mia. I have known her since i was 10 and we go through everything together. But the problem is she is in love with this little boy band called One Direction, and here is an even bigger problem, her cousin is Harry Styles, and he is a pain in the ass. But I fell for him anyways. It all started a year ago, when he came for a visit during the summer of 2012.
