Let's talk about the ugly aspect of human nature - neighbors聊聊丑陋的人性——邻居
Background introduction: My neighbor W is from a rural area. He has a junior college degree. After graduation, he worked as an IT outsourcing engineer in a big city for several years. Then he returned to the mainland to get married and have children. He lost his job and has been working at Meituan for seven years, earning about 3,000 yuan. He is over 40 years old. As for me, I'm a kid from the city, from a 985 university. After graduation, I worked for listed companies. Then I left my job at the age of 35 and was unemployed for many years. Now I have my own small company. We often smoked in the stairwell. We had known each other for five or six years and could talk about anything. I didn't guard against him (it was my fault). We would drink and get together occasionally. Before I started my company, I was unemployed for several years, so there was once a sense of sharing hardships together. During these years of dating him, there was a phenomenon that puzzled me all along: (Of course, now I know the reason. I'll keep you in suspense for now and see how you judge it. Please tell me in the comment section.)" I often run into his little boy or his wife in the community. At first, when I saw his child happily calling his name, he always avoided and never called me. A few times when he and his father were smoking downstairs, his father asked him to call me "uncle", but he didn't. But I knew that this kid was very outgoing and had many friends, but he just wouldn't call me. Later, when I met his child, I no longer greeted him proactively. His wife was the same. At first, when she met me, she would smile and nod, greeting me politely. But she pretended not to know me. After a few times, I no longer took the initiative to greet her. Can you guess why?
背景介绍：邻居W，农村人，大专生，毕业后在大城市干过几年IT外包工程师，然后返回内地结婚生子，失业，跑美团7年，约收入3000左右，年龄40+；我呢，城里孩子，985，毕业后都在上市公司工作，然后35离职后失业很多年，现在有自己小公司。我们经常楼梯间抽烟，认识5-6年也算是无话不说，我也不防着他（这是我的错），偶尔喝酒聚聚，我在搞公司之前也曾失业好几年,所以一度有一种共患难的感觉。
1）跟他交往这些年，有一个现象我之前一直很困惑：（当然现在我是知道原因了，我先卖个关子，看看你们是怎么判断的，请在评论区告诉我。）经常会在小区碰到他小男孩或他老婆，刚开始我见他孩子经常开心的叫他名字，他总回避，也从不叫我，有几次跟他爸在楼下抽烟，他爸让他喊我叔叔，他也不叫，但我知道他这个小孩是很外向的，朋友也很多，就是不叫，后来我碰到他孩子再也不主动打招呼了；他老婆也是，刚开始碰到我会微笑的点个头，礼貌性的打招呼，他老婆也是装作不认识，几次以后我也不再主动打招呼。你们猜猜这是为什么？
