Have you heard of the porcupine philosophy? The porcupine philosophy is that a group of porcupines gather together to keep warm in the cold winter. If they get too close together, their quills pierce the pigs, and if they get too far apart, they cannot achieve the purpose of keeping each other warm. Only by keeping a certain distance from each other and not harming each other can the warmth of the porcupine group be jointly maintained. The Porcupine Law tells us: The way to maintain a good relationship is to keep a certain distance - to be able to feel the other person's body temperature without being stabbed. Distance produces beauty. In life, this distance is called hazy beauty and harmonious beauty. Once the psychological space distance is violated, it will produce uncomfortable and unsafe feelings, and even become irritated. Therefore, we should try our best to avoid personal space being invaded and learn to handle personal space matters skillfully.
