The folded-paper contraption you worked with your fingers to tell someone their future. Pick a color, pick a number, and under the last flap was your fate — who you'd marry, or something rude your friend had written. The classroom fortune-teller you could make out of a single square of notebook paper.
The pencil-and-paper fortune game that predicted your whole adult life in a few minutes: who you'd marry, what car you'd drive, how many kids you'd have, and — the joke of the whole thing — whether you'd end up in a Mansion, an Apartment, a Shack, or a House.
The lost art of turning a torn sheet of notebook paper into a tightly folded packet — a triangle you could flick across the room, or a rectangle finished with a tucked corner someone had to pick loose — and passing it hand to hand when you couldn't just say it out loud. In a '90s classroom, a folded note was how a secret got three rows over.
