When Mr. A says that a certain X is “not necessary,” it is not that objectively “X is not necessary,” but that Mr. A subjectively “does not feel the need for it.”
Necessity depends on the situation.
If X is “useful but not indispensable” in a certain situation, those who do not understand its usefulness say it is not necessary, while those who do understand it say it is necessary. - A series of pictures of two people saying different things, no picture yet
