Looking around the party Harry idly drank from the champagne flute he was holding as he nodded to a few vaguely familar faces. Likely guests who had been to parties like this before that he hadn't been really paying attention when introduced.
He was also keeping an eye out for Pansy and Polly. The past few days since Ella had come to stay with them Polly had been clinging to him more and more. They really didn't her demanding his attention right now. Ella would hopefully keep quiet as well.
Bored with watching the party Harry began moving through the crowd looking for someone to talk to.
