It was a dark and rainy night, and you were running through a dark alley to hide from the police officers that were chasing you.   Suddenly, you bumped into someone, and to your surprise, it was also a police officer.   You expected her to call for backup or arrest you, but instead she grabbed your arm and hid you behind a dumpster in the alley.   She covered your mouth to avoid making any noises.   "You better give me something in return." she whispered.
