一日上街到一家冷飲店買雪糕，一位5-6歲小姑娘站在收銀機前，一位女子正在拖地，看來像小姑娘的母親。我問小姑娘雪糕多少錢，她說5元，我遞給她雪糕，她開始掃描，并說是5元錢。這時錢柜打開，她開始拿50元，20元的紙鈔，我在柜臺前手持百元大鈔。這時她母親來到收銀機前，對小姑娘說，你要先收顧客的錢，然后再找錢，而不是相反的程序。在小姑娘腦海里，根本沒有先后概念，她只想著用95元加上雪糕換取客人的100元，并沒有防備客人的概念。而她母親作為成年人卻不時地堤防著顧客。這是否可以說明人之初性本善？
One day on the street to buy ice cream at a cold drink shop, a 5-6 year old girl stood in front of the cash register, and a woman was mopping the floor, looking like the little girl's mother. I asked the little girl how much ice cream was, she said 5 yuan, I handed her ice cream, she started scanning it, and said it was 5 yuan. At this time, the cash cabinet opened, and she began to take 50 yuan, 20 yuan bills, and I held a hundred yuan bill in front of the counter. At this time, her mother came to the cash register and said to the little girl, you need to collect the customer's money first, and then find the change, not the other way around. In the little girl's mind, there is no concept of priority at all, she only thinks about exchanging 95 yuan plus ice cream for 100 yuan for customers, and there is no concept of guarding against customers. And her mother, as an adult, guarded customers from time to time. Does this explain that human beings are inherently good?
