A childhood belief about aliens

i was a rather gullible child, and my older sister was always taking advantage of this. once, she managed to convince me that i was a human alien hybrid (we watched a lot of x-files), and that our mother and father weren't my real parent's. she even mixed up a concoction of food coloring and put it in a vial and told me it was a sample of my blood. i cried for days.
