1. When you're babysitting the kids down the street.
2. When you head out to the woods for a weekend camping trip.
3. When you're sleeping.
4. When you're enjoying a nice relaxing shower.
5. Any time you're in a hospital.
6. When you have a child.
7. When the telekinetic girl at your high school prom gets upset.
8. When you have to go into the basement for something.
9. When you're driving.
10. When you're not driving...
11. ...and any time you're in a parking garage at night.
