Whenever I played outside my parents would say that I could go as far as I like, so long as they could see me. And that if I could see them, they could see me. Using this logic I came to the conclusion that by closing my eyes, they wouldn't be able to see.
Many of my friends also had parents that told them this, and we had all come to the same conclusion. This made playing hide and seek very confusing.
