“Not everyone has a voice. Many outsiders cannot speak through walls, and, as a consequence, they become silent and invisible. Some give up their voices willingly. Others cannot face the ferocious silence of their lives; so they replace their genuine voices with incomprehensible shrieks of rage. They bombard the wall with wrath or batter it with explosives. The silence is broken by their rage, but nothing changes. They remain outsiders who are desperate to be allowed into the world.”
