First of all, reciprocity means more than just gifts, giveaways and cash gifts. I think it refers to a polite communication. For example, when two people meet, one of them greets the other politely, while the other is arrogant, so you leave without paying attention. Actually, it's rude. You come and I go. For example, someone gives you a gift out of courtesy, but when you get here, others will stop doing this and you don't want to return the gift. In fact, you lack manners and manners.
Secondly, focusing on reciprocity can narrow the distance between us. At least, people will think that you are not a miser, and you will not think that you are uneducated and impolite. On the contrary, I will feel that I am a particularly sensible person and can be satisfied.
But we should also see that in modern society, the idea of reciprocity has been distorted by everyone, and everyone is comparing with each other. For example, if someone in a family gets married, others will give him a lot of money as a gift, which highlights the close relationship between the two sides. Then, when someone holds a wedding banquet, he must pay more money in return, so as to have face.
I'm not saying this is wrong, but I think you actually pay more attention to a kind of spiritual respect and closeness when surfing the Internet. But in today's society, it seems that reciprocity can only prove their relationship through money. I think this is a phenomenon of putting the cart before the horse.
I hope that in the process of getting along with others in the future, we should pay attention to reciprocity, and we should pay more attention to reciprocity, which contains spiritual communication, not money competition.
