Peter celebrated his birthday on one day, and two days later his older twin brother, Paul, celebrated his birthday. How could this be?
When the mother of the twins went into labor, she was travelling by boat. The older twin, Paul, was born first, barely on March 1st. The boat then crossed a time zone, and the younger twin was born on February the 28th. In a leap year the younger twin celebrates his birthday two days before his older brother.
A girl lives in a house with her parents. There is a cellar door in the house, and her parents warn her to never, ever, open it because she's not ready to see what's behind it.
What is on the other side of the door that her parents don't want her to see?
The girl is locked in the cellar. Her parents are both crazed people who thought the best way to protect their daughter would be by locking her in the cellar since she was born. On the other side of the door is the rest of the house, and the outside world.
