“Giggling Siblings!,” Reader’s Digest, June 2019, 82-3. “We were setting the dining room table for guests when my mother asked my brother, eight at the time, to get the napkins. He disappeared into the other room and then reappeared and placed the napkins. Minutes before the guests arrived, Mom noticed that next to each plate was one of her sanitary napkins.” In most variants I’ve seen of this contemporary legend, which goes back to at least the late 1990s, the child (usually male) is either three or four years old.
