From about the ages of 6 to 11, i was sure that i was an alien test-subject/princess, and that when i became a grown-up, they would abduct me and take me to their planet, making me the alien queen. I never told my freinds of this though, as i didn't want them to get jealous, and also, i didn't want my alien spectators to know i already knew their plans.
