People with inner cool thin will not be too nostalgic, because their rule is "don't dwell on the pain of the past". In order to protect themselves, they will build a heart wall in their hearts. For all the people who have communicated with them, they will not leave traces in their hearts, so you will always see new people around you and will not always look for old friends. For them, suffering does not need to be recalled, and they will never let themselves indulge in the past.
Step 2 be friendly to others
Be friendly to others, speak politely and be friendly to everyone. But there is a clear line that will never be crossed. Within the boundaries, you can communicate and play happily. Once you cross the line, you will immediately avoid it and will not continue to communicate with others.
If you are dissatisfied with others, you won't say it, and you won't try to improve your relationship. Instead, you will silently delete this person from your friends list, but you will still maintain a very friendly appearance at ordinary times.
Don't interfere in anything.
People who are indifferent in heart are more willing to stay out of it. In the face of the noise of others, people with inner cool thin will not stir up any ripples in their hearts.
Especially when something happens to others, people who like to watch the excitement will run to care about other people's affairs, while people who are indifferent at heart will not care at all. They prefer to spend their time on their own affairs, even if they are playing alone or in a daze, they will enjoy it more.
