It's simple, because everyone cares more about themselves than others. Everyone doesn't care how others are doing, what's wrong with others, as long as they are good, and they are afraid to mind other people's business. People in college become very realistic but cute, and sometimes I feel lonely. I feel that there is no such simple friendship and no one wants to walk into your heart. When a person walks on campus, there is always a little disappointment and melancholy. Think it over. Actually, I don't treat others like this. Why can I ask others? Love is relative. Only by giving your heart to others can you gain your heart.
