It all started innocently enough. Every Christmas, presents appeared under the tree, one or two bearing gift tags from Santa. Santa always brought Greg something special.
We were never the kind of family that leaves out milk and cookies out on Christmas Eve - after all, our last name is Cohen! - but around age eight Greg insisted. He felt it was the least he could do in return for the cool gifts. He was thrilled when Santa left a thank you note in return.
Due to the timing of his lost teeth, Greg never noticed that Santa's writing closely resembled the tooth fairy's. Every time he lost a tooth, he would leave it under his pillow and the tooth fairy would take it, always leaving a note on a hand-made TF notecard with the requisite payment.
