"Alright, everyone, hide!" Maya called out, her voice barely concealing the quiver of excitement she felt. She peered through the peephole, breathless, anticipating the moment her best friend walked in. The apartment was a rainbow of streamers and silly hats. A text. "Postponed." She crumpled, a little. Then, a grin cracked across her face, stretching so wide it almost hurt. She grabbed a handful of glitter and tossed it into the air, letting it rain down over the furniture. The feeling in her stomach was a strange mixture of disappointment and… an urge to do something *completely* ridiculous.
