For my nephew. He's six and just received his first regularly assigned chore: filling the ice cube trays. On the second day, he asked his mom why it was necessary to fill the ice cube trays, and so she explained that that very moment, his father was using the ice cubes he had made the day before, to have cool fresh drinks while he worked. His eyes got huge, and he was so overcome with happiness at helping his daddy that he began squealing.
