Betty Vivian by L.T. Meade

Betty's room was empty, and at that time of day was rather chill, for the three big windows were wide open in order to let in the fresh, keen air. Betty walked into the room still feeling that mysterious tingling all over her, that tingling which had been awakened by her sudden and unexpected love for Mrs. Haddo. That love had been more or less dormant within her heart from the very first; but to-day it had received a new impetus, and the curious fact was that she was almost glad to accept punishment because it was inflicted by Mrs. Haddo. Being the sort of girl she was, it occurred to her that the more severe she herself made the punishment the more efficacious it would be.

She accordingly sat down by one of the open windows, and, as a natural consequence, soon got very chilled. As she did not wish to catch cold and become a nuisance in the school, she proceeded to shut the windows, and had just done so -- her fingers blue and all the beautiful glow gone from her young body -- when there came a tap at the room door. Betty at first did not reply. She hoped the person, whoever that person might be, would go away. But the tap was repeated, and she was obliged in desperation to go to the door and see who was there.
