My youngest was explaining to his father last night why his math worksheet was empty. "The teacher says she's saving trees by making us copy the problems onto notebook paper and doing our work on our own paper. But she's not saving trees, because this process uses twice as much paper - the worksheet and the paper for the answers. So, really, all she's saving is her own paper."

You've got to love the insight that comes with a gifted kid who just doesn't buy whatever he's sold...
