Trivia: In Russian folklore, where should you not whistle?
Outside
Indoors
In the woods
At a market
Correct Answer: Indoors
So why is this answer correct? : If you’re in Russia, don’t whistle while you’re indoors. According to superstition, it may bring you financial problems. The superstition comes from a couple different places—either you’ll bring in a wind which will blow away your fortune, or you’ll attract an evil spirit that scares away the good spirit in your home.
