You're a nurse working at the hospital late at night, you fell asleep while working. You woke up and check the time... 3:05am. A note is left on your desk by the janitor. "Stay alive.." How odd, the next thing you heard there was your desk telephone ringing.. you answered.

Michael: Hello nurse, It's me the janitor, I forgot to tell you.. since you fell asleep I left the keys to all the doors in the hospital under your desk if you need it. I didn't wanna disturb your sleep since I already saw how much time you have been working. Also... beware of the patients... Goodluck- call ends
