#30: Monsters Under the Bed
There are certain things that are so true that somehow they transcend time and space. These are truths that everyone seems to know, no matter where they live: things like the fact that it’s bad luck to spill salt, if your nose itches it means someone is talking about you, and if you go outside with wet hair you’re going to catch a cold.
But this one is perhaps the most important in terms of safety. I mean, do you want the monster under your bed to grab your foot? Seriously, though, I am a grown adult and way beyond believing in monsters, and it still makes me nervous to sleep with my feet uncovered.
