I think my treehouse is haunted

Yeah, I’m pretty sure my treehouse is haunted.

My mom and I moved into this new house a few months ago. We used to live in the city. A small apartment on the 12th floor of a building downtown. We’d lived there my whole life, and I loved it. I had lots of friends in the building and taking the city bus to school was always interesting. I didn’t like to take it alone, but that only happened a few times, when my friends were out of town, sick, or for whatever reason got to school a different way that day. Strangers were funny when you had someone to watch them with. They were a lot less funny when you were by yourself. They could be downright scary.
