A tourist traveling abroad passed through the entrance of a tunnel, assuming the traffic police wouldn't bother him, so he boldly went through.At that time, he discovered a police officer following him at a distance, but didn't immediately step forward to stop him.He thought to himself: 'That means it's okay. So he walked through leisurely.'As a result, when he went through the tunnel, the police officer quickly rushed forward and said to him: 'Sir, I'm sorry, you violated the traffic rules, please accept the punishment.'He felt very strange: 'Why is this happening?'The police officer said kindly: 'Because I was afraid that a loud shout would make you panic. In the tunnel, trains are constantly coming, which is very dangerous and could lead to serious problems. So, you must always obey the traffic rules.'The tourist was shocked and grateful to the police, and never broke the traffic rules again. I suddenly remembered when I was a child, playing by the well in the countryside. It was a very deep well, more than ten meters deep. Falling into it was difficult to rescue. Far away, my mother saw me. She was terrified, but in that second, she was incredibly calm. She didn't make a sound, slowly and secretly approached, when she was very close, she quickly hugged me and then let out a loud shout, scolding me.After I grew up, my mother mentioned this matter, simply with one sentence to summarize:'In critical moments, you must remain calm.'So, when I accidentally saw the first story, I immediately thought back to the event that involved my life, which is deeply imprinted in my memory.In facing difficult situations, maintaining composure can help you calmly overcome them.
