Love is a beautiful thing. Husband and wife look at each other, which means that two people have been together for a long time and become more and more alike. In fact, they are not only appearance, but also personality and some habits. There is a colleague who fell in love with her boyfriend some time ago. It is really love in the city. It is possible that they hit it off very well, so they both know each other very well. They all like cats and dogs. They all do the same job. Because everyone is a designer, they don't bother each other when they work overtime. Instead, they help with takeout. Once this female colleague got angry at work, but her boyfriend didn't blame him. Because he knew it must be a customer, which made her very angry. This boyfriend knew exactly what kind of customer he met, because he had met such customers before.
There are also many people's tacit understanding reflected in other aspects. When I was in college, I had a classmate who was in a long-distance relationship for a long time, but the tacit understanding between them became stronger and stronger. Although the two people never explicitly said who should visit him on which day and who should come to whose city on which festival, the tacit understanding between them is very strong. They both know when to call each other, and they both know it's a good idea.
This is mutual encouragement and progress. In fact, in life, there are often things that the author understands very well between couples like this. For example, the other half just finished running, the other half brought drinks, or the other half was sick, and the other half immediately bought medicine or sent some snacks.
