The biggest difference between oneself and others' life is comfort. Living alone, you can do whatever you want and eat whatever you want. Don't worry that your actions will affect others. Living with others is different. There are always some constraints in doing things, and I am always worried that my actions will affect others, and that others don't like or even hate some of my actions. Moreover, people should keep a certain distance, and distance produces beauty. I have a friend. She has a very good relationship with her best friend. They think that the relationship between the two is so good that living together will not cause conflicts and enhance friendship, so they share a room. At first, they got along well. As time went on, their small shortcomings gradually emerged. At first, everyone understood each other. After a long time, it becomes a bit contradictory. It is normal for friends to have small conflicts, and neither of them cares much about solving communication. Slowly, small conflicts accumulate into big conflicts. One day, they had a big fight over a trivial matter and even moved their hands. Since then, their relationship has been broken. The sentence "distance produces beauty" is quite good. Everyone needs his own small space to hold some of his own shortcomings and secrets. Even the best girlfriends are the same. If two people get too close, it is easy to have conflicts and make themselves feel bad about each other, so the relationship will become more and more alienated.
