A stingy person will not only lose friendship, but also lose all the emotions in life:
No matter what kind of feelings, only in the interaction between two people can they heat up further. A person can have any shortcomings, that is, he can't let others think that you are a miser or a delicate egoist.
Many stingy people are always complacent, as if they took advantage of each other at a critical moment. This self-righteous "cleverness" is the greatest stupidity in life. Only through some necessary investment can feelings harvest a friendship that surprises you.
