Gifts are wonderful things, but without thought and sentiment they are just objects. Ever see a department store Christmas tree display with fake presents? The don't have any warmth because they weren't placed with love. There was no thought behind them. They are just empty boxes. Love makes an object a gift. Love once made a pink hockey stick the perfect present.
My son and daughter are both grown up now, successful adults with jobs and lives of their own. I suspect the reason I have kept their old teeth all these years is that every night the Tooth Fairy paid my kids a visit wasn't only a magical experience. For them, it was also a practical learning experience.
