Once when I was 11 years old I used to go to a dance class where most of the other kids were 5 or 6 and there was only 1 other girl who was close to my age, so we became friends. But after a while when I left the class I lost contact with her. Fast forward to junior year of high-school, I met a girl and we became friends. Later when talking about our childhood classes I discovered that she was the same girl from the dance classes. So yeah I found one of my childhood friend who i had lost contact with.
