['A friend of yours is being chased by a murderer. She comes to your door and tells you about this situation, then proceeds to hide. You know where she hides. A little while later, the murderer comes to your door and asks you where she is. What should you do?']

Liars have their part in the lake of fire, that burns forever and ever!
