1. One morning, while waiting for his tires to be replaced, an old man noticed something strange. A little boy kept pointing and giggling as he watched the workers pull out giant rubber bands from under the counter. Curious, the old man asked what those huge elastic bands were for. With a knowing smile, one worker explained they used them to test tire pressure quickly—much faster than using air pumps. The boy burst into laughter again, and the old man shook his head with a smile, thinking, ‘These kids these days never cease to surprise.’
