Once the streamers are hung, the playlist is going, and the punch bowl is fizzing, there’s really only one more vital piece to complete the party puzzle: the guests. As they file in, each reveler will ease into their respective comfort zones and, after a song or two, unleash their turned-up personas for all to see.
