Yesterday afternoon while walking back to class with a student, I spotted a quarter on the ground. "Look!" I said, tapping it with my foot since my arms were full. "A quarter." He stopped, looked at it for a few seconds, and shrugged. "Meh," he said and continued walking. "Then pick it up for me," I told him. "I'm not as rich as you are." He smiled and carried it to our room.
