人在世上生活,与绝大多数人只是平行线,永远没有交集;只与少数人成为交叉线,有一次交集;一直胶着在一起的恐怕只有数人而已。属于平行线的人群,被社会学称为次属社会,有机团结关系,陌生人等等,虽然你可能使用他们生产出来的产品,享受到他们的服务,但是没有见过他们(例如某本你读过的书的作者),或者见过却叫不上名字(例如你所住过的旅馆的服务生)。属于交叉线的人,只有短暂的结识,处于首属群体与次属群体之间,机械团结关系与有机团结关系之间,熟人群体与陌生人群体 People living in the world, with the vast majority of people are only parallel lines, never intersect; only with the minority become a crossover, there is a meeting; I am afraid there are only a few people who have been glued together. People belonging to parallel lines are referred to by sociology as subordinate societies, organic solidarity, strangers, etc. Although you may enjoy their services using the products they produce, they have not seen them (for example, you The author of a book that has been read), or seen but can not get a name (such as a waiter at a hotel where you live). Those who belong to the intersecting line have only short-lived acquaintances, between the primary group and the secondary group, between the mechanical solidarity and the organic solidarity, and between the acquaintance group and the stranger group
