My dead best friend

Hi, I'm Suzy. Today I am going to tell you the story of my dead best friend, and yes I know this sounds weird but it's worth the wait. It all started 6 years ago, so I was in 2nd or 3rd grade. We went on a field trip to the meuseum, it was really cool. We got assigned into groups of four and I was in a group with 1 girl (and me) and other 2 boys. I knew everyone in that group except for one of the boys. I asked the teacher who he was and she told me he was probably just a kid who got lost from another class. We asked all of the teachers there and they all said that they didn't know who he was, so we took him in just for the field trip and we were going to call his mom when we went back to school to get our things. Well, the teacher asked him his name, but he didn't say anything. He seemed like the type where he didn't talk much and that was understandable at the time because we thought he was lost. Then, I confronted him about it and he started to open up and we became really good friends.
