Gwen went back and forth several times about whether or not she should go, but go to the party she did, even dressing up for it, and a mask, as was required. While she loved wearing dresses, she always felt uncomfortable in them, like she was playing a part instead of being herself. And herself was usually the sporty, tomboy sort, not the sort to wear a silky dress and heels that made her look more like an Amazon than she already felt on a normal day. She didn't know Sirius all that well, but always enjoyed an excuse for a party -- that and she hoped she might be able to see Regulus. It was masochistic of her, of course, given their argument and the way she treated him (and vice versa, too, of course), but she -- well, she was being silly and such a girl, too.
