Life is like a ruler, you must have measure. Emotion is like a face, don't exceed the boundaries.
Between people, there should be a certain distance, far and near, self-determined, the principle is to make oneself happy and others relaxed.
Between family members, distance is respect; between lovers, distance is beauty;
Between friends, distance is care; between colleagues, distance is friendliness;
Between strangers, distance is courtesy.
Don't underestimate these life's distances, how many emotions finally fail because of distance.
Too far, dissatisfaction arises; too close, conflict arises.
Many people have such experiences and insights:
The closer the relationship with someone, the more frequent the friction and conflict, conversely, it's easier to get along with newcomers.
Family members and couples often complain about each other, this is a manifestation of the situation.
According to logic, the closer the interaction, the easier it is to get along, the better the interpersonal relationships, but in fact, it's not like that. What's the reason?
This can be explained by psychological 'hedgehog theory' (also known as psychological distance effect).

In a snowy winter day, there are more than ten hedgehogs shivering in the forest.In order to warm up, they huddled together, but because of the thorns, they quickly dispersed.However, the weather was really cold, so they wanted to get together for warmth, but the pain from being together made them have to separate again and again, dividing and reuniting, constantly struggling between freezing and being pricked.Finally, the hedgehogs found a suitable distance to warm up without being pricked by each other. This is an ancient story, which tells people to maintain a distance when interacting, only appropriate distance will bring joy.As for saying 'beauty comes from distance,' this is roughly the meaning.Distance, gives room for imagination, avoids each other's shortcomings, shows all the beautiful things to others.As the saying goes, there's no scenery in familiar places.Distance creates beauty, in fact, it's mutual respect, a vast sky and a spacious distance. When interacting with others, we should maintain a distance; It's not out of heart, but to leave a small space for the other person's heart, we have no right to invade others' privacy.It's not out of warmth, but to leave a little space for ourselves, to avoid being disliked because of excessive warmth.You should put your enthusiasm in the right place, you will eventually not be the same as others, others are not you.Tang Dynasty poet Han Yu wrote:Rain like silk in the small street, grass color is far away, close up is invisible. The meaning is that in the spring drizzle like silk, the grass sprouts, from afar, a hint of green;But when you get close, you only see a few grass buds, the green is difficult to see.Being too close can make you feel that things don't exist; to grasp something, sometimes you need to step outside of it; people's views and feelings about things are related to distance. Appropriate distance is the best way to express love.Distance gives you a sense of longing, distance keeps a certain emotion in your heart, makes a thought transcend time and space, lingering in your heart, love is not a shackle, nor a tool. Use distance to restrain love, that's the most appropriate care and friendship.Don't get too close, there's still your own life, don't get too far, just a turn of the body. Let's slowly approach, don't ask where you came from or where you're going, meet is enough;If the road is different, let's just pass by, and slowly move away;You still have your beauty, so that the next person will admire you deeply.
