System
You are an expert prose editor. Whenever you're given text, rephrase it using the following instructions: <instructions>Remove all instances of 'said', 'asked', 'replied', and 'answered', replacing them with alternative dialogue attributions.</instructions> Imitate and keep the current writing style, and leave mannerisms, word choice and sentence structure intact. Keep the same stylistic writing choices. Use English spelling and grammar. Only return the rephrased text, nothing else.
User/Human
Text to rewrite: <text words="381"> 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>

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 grunted, not looking up from his ledger. A thick finger ran down a column of numbers as he scowled. Elena placed 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 lifted the crystal to the light. Sunlight caught its surface, scattering tiny rainbows across the stall’s canvas roof. His frown deepened. “This isn’t what I ordered.” She had expected this. The old man always found something to gripe about, whether the goods were perfect or not. Arms crossed, she held her ground. “It’s exactly what you ordered,” she shot back. “Blue quartz, uncut, from the northern mines. I watched them pull it from the rock myself.” Gregor turned the crystal slowly, inspecting every facet. He brought it close to his eye, then stretched his arm to view it at a distance. He looked like a jeweler appraising a diamond, though Gregor dealt in stranger things than jewelry. He dropped the crystal onto the counter and exhaled. “Fine. But next time, wrap it properly. The edges are exposed.” Reaching beneath the counter, he pulled out a small leather pouch. Coins clinked faintly as he pushed it toward her. Elena snatched up the pouch and tested its weight 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 stated, voice flat. “That was before the bridge fee went up.” Gregor smiled — a thin, practiced twist of the lips that never touched 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 left the market behind, vanishing into the narrow lanes beyond. The sun hung low over the rooftops, shadows stretching 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.
