When I was a child, I often heard the elders say a word: It is rare for people to make one or two real friends in their lifetime.
At that time, I was young and thought: You are just too few people to know.
Later, I was older and knew the secrets of interpersonal relationships. I guess they might say that they want to express to each other: Your friend is very precious. It is a kind words.
After experiencing more things, it is more and more found that this sentence makes sense. Maybe people are lonely, it is difficult to open up to others.
Or maybe, first of all, you have to be a person worthy of deep friendship, so that you have the opportunity to make more real friends.
What kind of people are worthy of deep friendship? A brief summary, I also hope to discuss with you.
