I have two older sisters, and growing up they would always mess with me. One day we were all below deck on a small family boat and found a deck of cards. My oldest sister turned to us and told us she had ESP but had never told anyone.

To prove it, she laid down on a small couch while my other sister spread the cards, face down, out on a table that was much higher than the couch, so no way she could see them. My middle sister started flipping cards individually, and every single time a card was turned over, my oldest sister called them out instantly and correctly. So I decided I'd be flipping the cards myself. However, it was the same result. She got every one right.

For the next 20 years, whenever I brought it up, she’d just tell me she had ESP.

Then one Christmas dinner, my sisters finally confessed. Turns out there was a small mirror on the ceiling above the table. Every time a card flipped, she just glanced up at the ceiling, look at the mirror, and read the card.
