At the end of the day, bad luck laundry days are just stories. But stories are what connect us to our past and give our boring routines a little magic. So go ahead, wash your gym socks on Friday if you must.
Just don’t do it on New Year’s Day. And definitely don’t leave them out in a strong wind during a new moon. You never know what you might wash away. After all, it’s better to be safe than sorry—and your clothes will be just fine waiting one more day.
