You've been dating your girlfriend almost two years now. You often stay late over the summer and on weekends and arrive home long after the rest of your family go to sleep.
Every night, you drive the deserted rural roads back home from a pleasant evening at her house, but you become overwhelmed by fears that you will arrive home to find your family dead in their beds. Each night, you peek into your sister's room and see she's fine and hear the reassuring rumble of your father's snore as you pass your parents' door.
You chuckle at your silly worries and drift off to sleep. Finally, one morning, you decide to tell your mother about your late-night fears amidst some jovial conversation for a nice laugh. As you tell her, a concerned look comes over her face. She sweeps the hair away from her face as she says,
"Oh honey, you know we were all shot almost two years ago."
You scream as you see the gaping bullet hole in her forehead.
