In your opinion, which stories will make people tremble?

One afternoon when my daughter was three years old, while her daughter was taking a nap, her mother-in-law went to the market to buy food. After more than half an hour, my mother-in-law suddenly saw a strange woman looking for her with her crying granddaughter at the food market, and she was shocked. It turned out that my daughter woke up halfway and found no one at home. After crying for a while, there was still no one, so she opened the door and went to the slide in the community to find grandma, but there was still no one. She just stood there crying sadly, afraid and helpless. Her crying attracted a strange woman, and I don't know how they communicated. Anyway, this kind woman led her daughter to several intersections, found my mother-in-law in a large food market, and sent her child safely to her home. Mother-in-law was so flustered that she forgot to say thank you. Eight years have passed, and whenever I think of this terrible thing, I am grateful. Since then, I have tried my best to help strangers in need, because I have been blessed by God and strangers.
