The thing about whistling indoors in my grandma's culture - I always thought it was just superstition till last month
Grew up hearing my Lithuanian grandma say whistling inside brings bad luck, basically invites bad spirits or something. Always rolled my eyes, figured it was old world nonsense. Then last month I was on a job painting a basement for a Lithuanian family in Chicago. Owner's aunt shows up, I'm casually whistling while cutting in trim, and she literally stopped me. Grabbed my arm and said 'nešvilpk viduje' which I looked up later means don't whistle inside. She told me that in the old country, miners used specific whistles to communicate underground. Whistling a random tune could mess with the signals and cause collapses. So the taboo wasn't even about spirits originally, it was a practical safety thing for people who worked in mines. Never connected that before. Has anyone else found a real origin story behind a cultural taboo that made you rethink it?
