Rachel and her friend Daniel had planned a weekend trip to Paris. They arrived at the airport later than expected because of heavy traffic. When they reached the check-in counter, the agent said, "I’m sorry, but the gate has closed." They couldn’t believe it. Daniel felt frustrated, but Rachel stayed calm. She said, “Let’s check if there’s another flight today.” Luckily, they found a later flight with a few seats left. While waiting, they had coffee and laughed about their bad luck. “Next time, we’ll definitely leave earlier,” Daniel said. They finally arrived in Paris, tired but happy.
