Because

Because had not always demanded reasons. When she was young, she'd been a great announcer of things she couldn't back up.

She'd told her whole family, with total conviction, that the old willow by the creek was going to fall in the next storm. She felt it — the tree looked doomed to her, and she said so, loudly, for weeks. When someone finally asked her why, she had nothing: no lean she could point to, no rot, no cracked roots, just a feeling dressed up as a prophecy. And then a real question came from her uncle — not unkind, just direct: "What did you see that tells you it'll fall?" — and she stood there with her mouth open and nothing underneath, and the empty, exposed feeling of it burned. Not because he was mean. Because she suddenly saw that she'd been walking around with a roof and no walls, and had never once noticed the house wasn't there. She went and looked at the willow, properly — and found it was actually fine, deep-rooted, healthy. Her feeling had been pure weather inside her own head. From then on she made herself a quiet rule: before I say it out loud, I find the walls. If I can't point at the evidence, I don't get to make the claim yet.

She walked to the Grand Laboratory at twelve, drawn to the one place where "because of what?" was the most respectful question you could ask a person.

Smithy, the badger who ran the lab, met her at the door and held up two rocks. "This one's heavier," he said, nodding at the left. "True?"

The old willow-Because would have agreed to be agreeable. This Because did not. "I don't know yet," she said. "You said it's heavier, but I haven't seen anything that shows it. Let me build the walls." She set them on a balance. The left dipped. "Now it's true — because the balance tipped toward it. Before, it was just your word. Now it's got evidence under it."

Smithy set the rocks down, considering her. "Most young ones agree with the badger who runs the lab," he said. "You made me show my walls. You'll ask everyone that — including yourself. That's exactly the habit this whole place is built on. You belong here."

Over the years, Because's bench filled with kids carrying loud opinions on wobbly legs.

One afternoon a boy stormed up, certain. "My experiment proves sugar water makes plants grow faster. It's obvious." Because didn't tell him he was wrong. "Show me the walls," she said. "Because of what?" He hesitated. "Because... the sugar-water plant is taller." "Good — that's one wall. What else? Did you measure both at the start? Same light? Same amount of water otherwise?" The boy's certainty flickered. "...I didn't measure the start. And the sugar one was already on the sunny sill." "Then here's the honest thing," Because said, and her voice stayed warm. "Your claim might still be true. But right now it's standing on a wall you built and a wall that's actually just sunlight wearing a sugar costume. You can't tell which yet." The boy deflated, then — slowly — brightened. "So if I redo it, same light, measuring the start... then I'd actually know?" "Then your claim would stand on its own legs," Because said. "And that's a claim you could defend against anyone, because you'd know exactly what's holding it up." She touched her charm. "It's not enough to be right. You have to be right because of something — something you can point at." The boy went to rebuild his experiment, and Because watched him trade a loud, wobbly certainty for the quieter, sturdier kind that comes from knowing your own walls.
