Daphne would have minded much less if she wasn't being put under this pressure with her NEWTs right around the corner, but her family had always had high expectations. She had to get good grades, have some sort of career so that she could take care of herself in a worst case scenario, and she was also expected to marry some nice boy (preferably pureblood, but an especially ambitious and bright halfblood boy was acceptable to them).
She considered all the things she needed to get done, and then considered how much of a pain it would be if Pansy got offended any further. The decision was an easy one to make.
"I would be glad to. After all the work I've been putting in, it's entirely reasonable to buy myself something nice. And if you see anything you like, you can drop hints for your birthday."
