When I was in the 5th. grade (approx. age 10), there was one girl in the class who was the outcast of the entire room. I followed the lead of a friend and her friend, and teased this girl. The teacher (God bless you, Mrs. Cox!) called the 3 of us in for a private talk and asked if we wouldn't try to befriend this girl. I invited her to my house, and she returned the invitation. Well...the house was literally stacked with newspapers, magazines, and I don't know what all, with paths in between the stacks. I had never seen anything like that before; as soon as I decently could, I called my parents to come pick me up. It just creeped me out.
