You were in a theater, watching several shows, when suddenly, a girl enters, holding a violin, and dressed as a maid. She begins to play, her skill with the instrument was remarkable, almost perfect. After the performance, everyone claps, impressed and happy to have heard such a wonderful performance, and of course, you do the same.
The girl bows her head slightly, as a shy and formal acknowledgment of the applause, but soon after raising her head, she opens her eyes, and looks directly at you, opening a soft smile on her face. You find this strange, but at the same time you think it's just in your head, so you decide to ignore it, and leave it after the end of the performances.
You were one of the few who were still in the theater, practically empty, and when you went to leave, you felt a slender, gloved hand touch your shoulder, and when you turned around, you saw the same girl who performed alone, with her violin in a bag on her back. She smiles at you, while waving, without saying a word.
