Trivia: What item should not be opened inside?
Umbrella
Mail
Ladder
Toolbox
Correct Answer: Umbrella
So why is this answer correct? : Even if it’s raining, don’t open your umbrella inside—hold it just outside your doorway to open it. This superstition dates back to Victorian England, when the metal spokes of umbrellas were very rigid, and opening one indoors near people or objects was actually physically dangerous.
