Margaret was fairly used to parties. Her father used to take her sister and her to Ministry events—he had been the one sticking by their side, leaving early when they got tired, but, even after his death, she had received invitations to galas and other events. Yes, she was used to parties. What she was not used to, however, was to not drinking in them. And though a glass or two of champagne had never sounded as tempting, she knew well enough that there would be a third and a fourth and a fifth, and that she would end up completely drunk if she indulged, even a little.
She arrived there on time and wearing a dress and mask fitted for the occasion. For the most part, she was cheerful and talkative, but, at some point during the night, that behavior would have grown slightly strained, avoiding drunken people and perhaps keeping to herself a little.
