She heads back to the party.

Anna returns to the party proper, which has gotten a little rowdier as the music picks up and the drink flows. There isn't really room to dance, but people are doing it anyway, crushed together happily in the middle of the floor.

Everyone's gotten pretty loose by now, individual groups dissolving into a relaxed, happy crowd. Anna wanders round and round the room, passing through half-a-dozen different conversations, swapping small-talk and rambling anecdotes with people she vaguely knows.

The party continues on its merry way for another couple hours, but like all good things must come to an end. The crowd is starting to gradually thin out as people begin saying their goodbyes, the ambience changing slowly but unmistakeably as they slip away home in ones and twos.

Finishing her drink, Anna places the lipstick-smeared glass on the sideboard, surveys the room and contemplates her options.
