The teacher stood with his back to the classroom, writing a list of spelling words on the white board for his young students to review. Busy hands in the back row deftly folded a loose sheet of paper and sent it sailing forward, spiraling round overhead and landing within a couple feet of where the teacher stood. Discreet giggles quickly turned to collective breath held, and somewhere in the back a young man slid down in his seat. Retrieving the aircraft from the floor, the teacher couldn't help but smile inwardly, noting how well the plane had been crafted and remembering the paper-folding days of his own childhood years ago. Holding the airplane high overhead, he sent it sailing in a wide arc across the room while announcing that the student sitting at the desk where the plane landed would be permitted to choose a sticker from the prize box, as would the crafter of such a fine airplane, however any future flights would need to take place on the playground outside.
