My older brothers did not want me, their little sister, to play board games with them. They told me that the (recommended) age on the box meant I couldn't play unless I was that age or older because it was against the law and I believed it and thought the games had tiny little policemen inside of them that would pop out and arrest me if I played it. I believed this for a really long time.
