Rewrite the following passage from past tense to present tense. Change every narration verb from simple past to simple present. For example: - "walked" becomes "walks" - "ran" becomes "runs" - "knew" becomes "knows" - "would not wait" becomes "will not wait" - "had agreed" becomes "have agreed" Important: - Do NOT change dialogue content inside quotation marks. Characters speak in whatever tense they speak in — leave their words exactly as written. - DO change dialogue framing verbs: "she said" becomes "she says". - Do NOT change present participles (e.g., "examining", "appraising") or adjectives — they are already in the correct form. - Preserve correct subject-verb agreement: "she walked" becomes "she walks", "they walked" becomes "they walk". - Change nothing else. Preserve all other text exactly as written — same words, same punctuation, same paragraph structure. Return only the rewritten passage, nothing else. <text> The market square buzzed with the sound of a hundred voices. Elena pushed through the crowd, her satchel clutched against her chest. She knew the merchant would not wait — he never waited for anyone, least of all a girl from the outer ring. "You're late," Gregor said, without looking up from his ledger. He ran a thick finger down a column of numbers and frowned. Elena set the package on the counter. "The bridge was out. I had to take the long way around." "Not my problem." He unwrapped the cloth and held the crystal up to the light. It caught the sun and threw tiny rainbows across the stall's canvas roof. Gregor's frown deepened. "This isn't what I ordered." She had expected this. The old man always found something to complain about, whether the goods were perfect or not. Elena crossed her arms and stood her ground. "It's exactly what you ordered," she said. "Blue quartz, uncut, from the northern mines. I watched them pull it from the rock myself." Gregor turned the crystal slowly, examining every facet. He brought it close to his eye, then held it at arm's length. Elena thought he looked like a jeweler appraising a diamond, though Gregor dealt in stranger things than jewelry. He set the crystal down and sighed. "Fine. But next time, wrap it properly. The edges are exposed." He reached beneath the counter and produced a small leather pouch. The coins inside clinked as he slid it toward her. Elena scooped up the pouch and weighed it in her palm. It felt light. She loosened the drawstring and counted: eight silver crowns. They had agreed on ten. "We agreed on ten," she said flatly. "That was before the bridge fee went up." Gregor smiled — a thin, practiced smile that never reached his eyes. "Take it or leave it." She took it. She always took it. The outer ring didn't offer many choices, and Gregor knew that as well as she did. Elena walked out of the market and into the narrow lanes beyond. The sun hung low over the rooftops, and the shadows stretched long across the cobblestones. She slipped the pouch into her satchel and quickened her pace. If she hurried, she would reach the bridge before dark. </text>
