For a while when I was eight years old, a girl in the grade below me lived next door. Her name was Tacie. Because we lived next door to each other, we became "best friends".

We decided to make some sort of carnival in our backyards (very big backyards, for the record) but differed in opinion on who would be invited to participate in the carnival activities. I thought her slightly younger brother, David, should be included. Tacie didn't.

Because of this misunderstanding, our friendship ended. And then David was my new "best friend" until their family moved away not long after.
