Some prisoners spent more than ten years buried in solitary cells the size of coffins, hearing nothing but clanging bars or footsteps in the corridors. . .[they] survived because they could talk to each other by tapping on the wall. In that way they told of dreams and memories, fallings in and out of love; they discussed, embraced, fought; they shared beliefs and beauties, doubts and guilts, and those questions that have no answers.
When it is genuine, when it is born of the need to speak, no one can stop the human voice. When denied a mouth, it speaks with the hands or the eyes, or the pores, or anything at all. Because every single one of us has something to say to the others, something that deserves to be celebrated or forgiven by others.
