I used to believe that if you kissed a boy at a young age, that boy will be your sweetheart when you become a grown up, no matter what. I saw a little girl kiss 3 boys in a row and they all ran screaming in horror. I then wondered how someone could have 3 sweethearts and believed that until I was 9. I'm 10 now.
Still have no idea where that belief came from. I'm a strange kid.
