Of course, the most important thing for us to find a bosom friend is to have similar personality and hobbies with him. As the saying goes, "It's fate to meet thousands of miles away, but we never meet." If you have different views on each other and different personalities, even if you live with that person, you can't be bosom friends. Just as we stay at school, there will be examples where we are not friends with our roommates. That's because you two don't have the same. Many times, we will become bosom friends after traveling online or meeting someone briefly, just like the feeling of meeting someone briefly. This shows that if you want to have a particularly close friend, you need to find a friend who is in tune with you and has a similar personality. Slowly, I believe you will become very close friends.
We are not blindly looking for friends, especially bosom friends. Be sure to remember that there are not too many intimate friends, two or three are enough, because friendship, like love, can also be jealous. If you have too many intimate friends, the other person will think who you are and have the same attitude, and he won't want to tell you what he is thinking. Emotional things are mutual and need to be refined.
