User/Human
Text to rewrite: <text words="283"> Mara didn't want to be there. She'd promised herself she wouldn't go back, but here she was, standing in the lobby of the building she'd left three years ago. It wasn't supposed to feel this way. "You're late," said the receptionist, a young man who didn't look up from his screen. He'd been typing something, and he didn't stop. "She's waiting in the conference room. You'll want to hurry — she's not in a good mood." Mara couldn't tell if that was meant as a warning or just small talk. She wasn't sure it mattered. She'd made her decision, and there wasn't any point in second-guessing it now. The hallway hadn't changed. The same grey carpet, the same harsh lighting, the same faint smell of coffee that'd been sitting too long. Mara wouldn't have been surprised to find her old nameplate still on the door, but it wasn't there. Someone else's name had replaced hers. "I didn't think you'd actually come," said Priya, who'd risen from her chair the moment Mara entered. She wasn't smiling. "We've got a problem, and you're the only one who can help." "I'm not sure that's true," Mara said. "I haven't been involved in the project for years. I wouldn't know where to begin." "You'd be surprised," Priya said. "It's the same codebase. They haven't touched the core modules. You'd recognize it instantly." Mara didn't answer right away. She'd already told herself she wouldn't get pulled back in. But she hadn't expected Priya to ask in person. That wasn't fair — it's harder to say no to someone's face. "I'll think about it," she said. That wasn't a yes, and they both knew it wasn't a no either. </text>

Mara did not wish to be present. She had sworn to herself that she would not return, yet here she stood in the lobby of the building she had left three years earlier. It had not been intended that it would feel this way. "You are late," said the receptionist, a young man who did not look up from his screen. He had been typing something and did not pause. "She is waiting in the conference room. You will want to hurry—she is not in a good disposition." Mara could not determine whether that remark was meant as a warning or merely as casual conversation. She did not think it mattered. She had already made her decision, and there was no point in reconsidering it now. The hallway had not altered. The same grey carpet, the same harsh lighting, the same faint scent of coffee that had been left too long. Mara would not have been astonished to find her old nameplate still affixed to the door, but it was not there. Someone else’s name had taken its place. "I did not expect you to actually come," said Priya, who had risen from her chair the moment Mara entered. She was not smiling. "We have a problem, and you are the only one who can assist." "I am not certain that is true," Mara replied. "I have not been involved in the project for years. I would not know where to begin." "You would be surprised," Priya said. "It is the same codebase. They have not altered the core modules. You would recognize it immediately." Mara did not respond right away. She had already told herself she would not be drawn back in. Yet she had not anticipated Priya asking in person. That was not fair—it is harder to refuse someone face to face. "I shall consider it," she said. That was neither a yes nor a no, and both of them knew it.
