‘Well, eighteen, then. And I saw you with him the other night at the Opera.’* She laughed nervously as she spoke, and watched him with her vague forget-me-not eyes. She was a curious woman, whose dresses always looked as if they had been designed in a rage and put on in a tempest. She was usually in love with somebody, and, as her passion was never returned, she had kept all her illusions. She tried to look picturesque, but only succeeded in being untidy. Her name was Victoria, and she had a perfect mania for going to church.
I would like to know what does " forget-me-not eyes“ here mean. Thanks.
