Here's a brief summary of the text in English:
At midnight, Professor Higgins and Colonel Pickering were still awake after a busy day filled with an ambassador's party, dinner, and an opera, during which they had showcased Eliza to high society. Eliza, dressed elegantly, seemed tired and overlooked by the men, who were more focused on celebrating their success in winning a bet regarding her transformation.
As they talked of their achievements, Higgins expressed his fatigue, and Pickering pointed out the success of their endeavors, even mentioning moments when he felt anxious about Eliza performing better than real upper-class women. After their conversation, they decided to go to bed, leaving an upset Eliza alone, who was frustrated and hurt.
When Higgins returned searching for his slippers, Eliza angrily threw them at him, demanding to know what would happen to her now that she had won the bet. A heated exchange followed, with Higgins dismissing her feelings and only caring about the bet's outcome. Eliza questioned her ownership of her clothes and belongings, revealing her fear of being seen as stealing. Their argument escalated until Higgins, losing his temper—a rare occurrence for him—decided to end the conversation and go to bed, while Eliza resolved to pack her things, asserting her independence.
