Lavender was ready to walk out and leave Pansy to her angry little tirade. She was no Hermione and if Pansy wanted to take out her wrath and frustration on the house elves so be it.
When she actually spoke though, Lavender took a closer look at the girl. Pansy looked as cold as ever, but her voice gave her away. It was probably completely foolish of her but her empathy won out over her good sense and she walked over and hugged Pansy. "I'm sorry, Pansy."
