I was driving to a tourist attraction and couldn't find a parking spot for ages. Just then, a young man came up to me and said, "Need parking? 20 yuan." Although it seemed a bit expensive, I still paid him 20 yuan. What the young man did next really taught me a lesson. He calmly drove away, making room for me. I realized I could do the same. When I was about to leave, I knocked on the window of a car that was looking for a parking spot: "Hey buddy, need parking? 30 yuan." Having successfully found a parking spot, I happily drove home!
