What is the scariest thing you have ever experienced? ____

This is the following thing.

When I was in college, I was waiting for the subway at a subway station. There was a very beautiful girl standing next to me. She was sweet-looking and very fashionable. She was holding a bag of fried chicken steaks and was minding her own business. Eat with the sticks tied. Then I noticed a woman standing next to the girl, about thirty years old. She was holding a six or seven-year-old naughty child in her hand, which I heard was her son.

Friends in Beijing should know that some Beijing subway stations do not have guardrails, and the naughty kid looks very active, laughing and jumping up and down. The woman is afraid that he is in danger, so she drags him and scolds him. The little boy made a fuss for a while and then noticed the girl eating fried chicken. So he stretched out his hand, pointed at the girl who was eating fried chicken steak and shouted to her: Mom, I want to eat chicken steak!

The woman glanced at the girl and said half-jokingly: Go and tell your sister to give you the fried chicken steak. The little boy turned his head and said to the pretty girl, "I want to eat chicken steak!" The pretty girl heard the sound, glanced sideways, and then turned her head without saying a word.

The woman was a little embarrassed, and the little boy started jumping up and down again, clamoring for fried chicken. I heard the woman mutter, "Who is he? He's dressed like a young lady." Then the woman grabbed the little boy and kept comforting him: "Good boy, don't make trouble. Let's stop making trouble. Mom will buy it for you when you go out later."

After that, I heard the sound of the subway entering the station. The subway was approaching from a distance. Just when it was about to arrive at the station, the little boy suddenly broke away from his mother's hand, ran forward, and pushed forward with all his strength. He hit the girl, who screamed and was about to be pushed off the platform.

Fortunately, because I had been secretly peeking at the girl, I noticed something was wrong when the little boy ran towards her. Just when the girl was pushed and almost fell off the platform, I took a step forward and grabbed her arm. And just a few seconds later, the subway, carrying a gust of wind, passed in front of us like a steel giant, and then stopped.

Everyone around them was startled. The girl was so frightened by what happened suddenly that her face turned pale and her lips trembled slightly. The naughty child's mother was also shocked. However, she did not step forward to comfort the girl or scold the naughty child. Instead, when the bus arrived at the station, she grabbed the little boy and squeezed into the car, disappearing into the crowd in the car.

After that, the girl didn’t get on the subway, so I sat with her on the steps for a while. She was a little confused, then sat on the steps and cried, and then kept thanking me. It's been a long time since it happened, but I still can't forget that moment, the girl's shoulders shaking slightly as she cried.

Some people say that human nature is inherently good, while others say that human nature is inherently evil. However, I have always felt that the world is so big, and that good and evil always exist. Some evils are planted since childhood, waiting to explode one day and cause harm. Only if you kill someone will they be discovered and punished. Human nature is so weird, and what makes me even more frightened is that you have no idea what kind of skin these evils are hidden under.
