Is it only tears that know love?

Many times, the past is impossible to miss. Maybe, there are always things that stay at the bottom of life, traces of varying depths. When the heart brushes by, it no longer feels pain, only a sense of numbness. Drinking coffee, with its bitter taste. I remember someone once said: "When your tears can't be held back and are about to fall, open your eyes wide, don't blink, and you will see the whole process of the world becoming clear to blurred. The heart becomes lucid and clear at the moment when the tears fall!" Love for a long time becomes a habit; Pain for a long time leaves a mark; Hate for a long time becomes a burden. A love without passion gradually shifts from fiery to plain, perhaps this is the kind of eternity we have been seeking all along.
