Crying and laughing are not speech or silence. They are a third category, created from a sudden inability to formulate a sentence combined to desire to react in some from.
Crying and laughing are forms of speechlessness (and I would consider calculated silence one of the tools of speech).
Crying is a kind of oneself. Emotion breakout and express themselves violently, heedlessly. But this violence is sometimes, for brief periods, necessary so that we can heal ourselves.
After the tears have flown then we should recompose ourselves and return to our familiar face, the one cherished by others. The pain and grief may not be over yet. But we can talk about it, reflect on it in order to walk back into the texture of our life.
Tears by themselves do not heal us. We must heal ourselves from them.
