How to keep a distance from friends of the opposite sex?

Friends need to keep a certain distance. No matter what kind of friends you are and how close you are, distance is so important. Friends, you need to manage with care, you need to have certain artistry, not preaching, but having personal experience. Don't pay too much attention to a friend, whether he is a boyfriend or a girlfriend, otherwise the other person will feel great pressure and will be overwhelmed by your attention, but you can't be too negligent, too negligent, and there may be no more contact. Some friends, if you value them too much, will make them feel tired to make friends with you and make themselves very hard. No matter between friends or lovers, the feelings for each other are definitely unequal. There will always be one who pays more, and the vulnerable one is often the one who pays more. So now many times I will tell myself to control my efforts so that my friends and I will not be hurt. So I won't force others now, and I will try not to bring pressure to others. Not all people in life can be friends. Everyone has his own attitude towards life, lifestyle, hobbies and personality characteristics, and he also has his own standards and conditions for choosing friends. The principle of making friends is to pursue spiritual communication. I often think that people can't live in the world without friendship, mutual help, care and support. When friends encounter difficulties and setbacks, it is much more useful and reliable to lend a helping hand to help each other tide over the difficulties than to send precious gifts. Being a friend is an obligation to solve problems and be happy.
