It's easy to make friends. Everyone you know can be friends as long as they are not enemies, but they are all casual acquaintances. You can't share your joys and sorrows. But a friend who can share or share everything with you at any time is not so easy to find. Just like a lover can only have one in his life, true friends are rare. I think the most important thing to be a friend is to be sincere. When you pay your sincerity, I want to be recognized by you.
