“It’s like dust. You walk about and don’t see it, don’t notice it, but it’s there and it’s all coming down, covering everything. You’re breathing it in. You touch it. You drink it. You eat it. But it’s so fine you don’t notice it. But you’re covered in it. It’s everywhere. What I mean is, we’re afraid. Just stand still for an instant and there it is, this fear, covering our faces and tongues. If we stopped to take account of it, we’d just fall into despair. But we can’t stop. We’ve got to keep going.”
