My first problem

Everything was going fine. My life was ok, I had friends and good grades. Today ,however, was the start of my first problem. We got a new student in my math class. His name was Kylan. Everyone else thought he was great, but I didn't. Now don't say I was judging a book by its cover because I knew this guy personally. He wasn't a new guy to me. He went to my old school and was in my class in 3rd grade. Not to be rude, but he was not very smart and he was one of the school bad boys. One time he got in trouble for a stupid reason. He was selling the snack Twinkies to students for a very high price. He got caught selling them and teachers got mad at him because we had a rule where you couldn't sell things to other students on campus. He got in a lot of trouble and had to return all of the money even though the students that bought the snack got to keep it. This may not sound too bad, but I shortened the story. Anyway I was always seeing him in trouble at my old school and I didn't want that trouble here. He never caused me trouble, but he scared me because he was a bit violent. I also liked that I had a new life away from my old one and didn't want anyone from my old school to be here at my new one. To make things worse, our math teacher sat us next to each other. I wasn't happy at this and I think he could tell. I acted a little cold towards him. After a few weeks though I slowly started talking to him. I have a problem where I could talk to anyone. When I'm bored I just start talking to random people about anything. That is how I became popular at my old school because I was friendly towards everybody. The new school I was going to was for rich students, but I definitely wasn't rich. Anyway the school had a lot of money and so they gave everyone their own personal school computer. We were allowed to have a few games and we could play them in our free time. I always got my work done early and Kylan did too. I always wondered how he finished a few minutes after me almost everyday, but I never questioned it. Anyway we sat by each other and we finished at the same time so we of course played games together since most of our games were two player games. The game we played the most was uno. We played that one almost everyday. I don't know why I became so close to him like friends only after a few weeks even though I knew how he acted. This friendship of ours continued for another week or two until my second problem came along.
