How can a couple not say anything?

I don't ask+you don't say = this is the distance; I asked+you didn't say = estrangement; I ask+you say = trust; You don't say+I don't ask = this is the tacit understanding; I didn't ask+you said = this is dependence. When the heart is near, words and deeds will be as natural as running water; If the heart is alienated, words and deeds will only be as dim as the tree of Sanqiu. Not afraid of isolation, the heart is in the north and south!
