When I was a child, people often said, "Once you enter society, no one will indulge you." Only after truly entering society did I realize that most people in society won't scold you for no reason. Many people think the biggest characteristic of society is indifference, but in fact, the biggest characteristic is boundaries. No one has that much time to manage you, educate you, or criticize you. The vast majority of relationships are built on interests, cooperation, and rules. What truly drains your emotions over time is often not strangers, but those who are closest to you and have the blurriest boundaries.
