The Secret

It was my best friend's deepest, darkest secret and it would be a hard one to keep.
His name is Francis, were best friend since i was 5 years old. His 1 year older than me, we grow up in the same hood. Almost everything we do, we do it together and if there's a team playing we two always at the same team. When i turn 8 years old and he was 9 his mother decided to leave to another place not so far from our hood. That's the first time were separated, but he came back like 2 years after. He was 12 years old and i was 11 and when we see each other again we were so like "is that you, man you grow a lot ha ha ha ha". We spent the year together doing stupid stuff. When we were chilling in the side walk near my house and something pop up in my mind. I ask him "why did you came back"? the expression of his face change and like his thinking very deep. He said "Michael can i tell you something that you can't tell anyone. His face is so serious and I'm so confuse while looking at him. He talks again "i killed someone in the place where we transfer that's why i came back" he smiled to me like nothing serious about he said. After that confusing conversation he said that a secret and we go home. Next day a heard my mom and some neighbor talking about someone who got killed. I step in and ask what happen mom? my mom said that their was a 15 year old boy killed by a knife in somewhere Francis transfer but no body know who did it. After my mom told that thing i remember what Francis told me before that day. The news was all over our hood. In that day i meet Francis in the place we usually meet. I ask him if he heard the news running all over our hood, he said yeah and his face was like nothing special about it. So i think that his not the one who killed the boy because he don't have any reaction about the news. In that day we spent the day doing nothing just lying in the grass looking at the sky. Finally he talked "remember i told you about i killed someone" I said yeah, why? The news that a boy was killed was true and I'm the one whose responsible for the crime. Francis told me that, if i were his real best friend I'm not going to say anything. I was so shock that my best friend was a killer and i don't know what to do. Am I going to keep or not, I want to keep it because i don't want my best friend to be put on jail but i want to tell the police because i want the boy and his family find the justice. After all of it i decided to keep it as our secret but every single day me and Francis are together its not the same feelings, I'm not comfortable.
