That's good advice.

Indeed.

Here's a short list of other things you could run into with the lights out at night:

1. An axe-wielding maniac.
2. A table with pointy corners.
3. A beloved pet that will no doubt be scarred for life afterwards.
4. Drunken rabble.
5. A rug made by your grandmother.
6. The door.
7. Another person running around in the dark at night with the lights out.
8. The cord connected to your phone, computer, or other expensive electrical device, that you will inevitably trip on and drag forward, pulling said object down to the floor with a mighty crash, rendering it broken forever.
9. The refrigerator.
10. Stairs to fall down.
11. Stairs to fall up.
12. The edge of a dock.
13. A trapdoor.
14. The hole that leads to Wonderland.
15. A vampire, werewolf, or other monster that wants nothing more than to destroy you.
16. That person you've been avoiding for weeks now.
17. Treasure.
18. Spiderwebs.
19. The wall.
20.  Trouble.

And that's only the beginning.
