Eliza twirled in front of the mirror, admiring the way her dress flowed around her. The anticipation was palpable, a fizzy energy coursing through her. Today, she was having a formal birthday celebration, a fancy dinner at a renowned restaurant, and a night of dancing.

She had chosen the finest restaurant in town, hired a string quartet, and invited only her closest friends and family. The prospect of an evening filled with sophisticated conversation, delectable food, and beautiful music filled her with a lighthearted warmth. She felt ready to burst with anticipation.

Her phone buzzed, a notification from her sister, detailing the surprise party she was also throwing that evening. Eliza's shoulders slumped ever so slightly.
