You're a psychiatrist at mental hospital, your supervisor always belittled you by yelling at you, once he even yelled at you in front of an patient, a few weeks later you went to work like normal and walked straight to the elevator, but the elevator door took forever to open, you decided to take the stairs, but in that exact moment, the door opened, patient was standing over your boss holding a bloody knife, your boss was dead

"Did you think i forgot the way he yelled at you in front of me?"
