Well, I personally think that even if the relationship is very good, it needs to be maintained. A good friendship must be accompanied by good people. Even if friendship is shared by both parties, it is not wishful thinking of one party. So be sure of your friendship and make sure that the other person attaches great importance to you. Just as you value her, you can greet her regularly after a while. Another thing is that friendship is like love. You should be nice to him and make him think that you are different from others. The third is to remember to give some gifts on your friend's birthday, which can be inexpensive, but not too perfunctory. The fourth is that you should know her hobbies and know her taboos. Love and friendship are similar, so we should cherish them.
