Everyone has a different way and depth of making friends, and some people prefer to maintain superficial socialization rather than deep relationships. This choice is a matter of personal preference and personality trait, and does not mean that they are not worthy of dating or are not good friends.
Some people may prefer to maintain a relaxed and enjoyable social relationship and enjoy communicating with others, but do not want to involve too much personal privacy or invest too much emotion and energy. This does not prevent them from building friendly relationships with others and deriving joy and support from them.
It is important to respect everyone's choices and boundaries. If you feel that the person you are familiar with is not willing to make a deep friendship, you can respect their decision, maintain a superficial relationship, and enjoy each other's company and communication. There is no need to force or expect them to change, but to accept each other's differences and maintain a friendly relationship.
At the same time, it's also important to remember that everyone grows and changes, and their way of communicating and attitudes may change over time. Sometimes, by giving them some space and time, they may also take the initiative to show more truth and depth.
In conclusion, relationships are diverse, and everyone has their own unique ways of interacting and needs. By respecting the choices of others and maintaining mutual understanding and support, we can build harmonious and healthy social relationships.
