That boy that I once knew

We were best friends since preschool. He was like a brother to me and very protective. We would always have play dates and sleep overs. He was my only friend, but I didn't care at least I had him. In elementary we would always play tag with the other kids and sometimes he would tag me first if he was first it. In middle school we would always hang out at lunch and I would always sit at his table with his other friends. In 9th grade we started fading away each day. Sometimes I would sit at another table and he wouldn't do anything. He would ignore me most times and pay more attention to his other friends. Then high school came........ He was the popular kid in school and i'm at the bottom of the list. The most bullied kid in school and when he would see me getting beat by the cheerleaders he would look at me and keep walking like he didn't know me. When ever I said Hi to him he would glare at me and keep walking. Then one day something snapped in him. He started bullying me like the others and I have no idea why. I would try to get away from him, but I couldn't he was too quick. That's when my best friend that I knew ever since we were kids was now a stranger and a bully. What happened to that boy that I once knew. Now we're strangers and he faded away from me and that boy is Harry Styles.
